TEA1530AP/N2,112 - NXP Semiconductors / Philips Semiconductors

1. General description

The GreenChip II is the second generation of green Switched Mode Power Supply

(SMPS) controller ICs. Its high level of integration allows the design of a cost effective

power supply with a very low number of external components.

The TEA1530(A) (TEA1530T, TEA1530AT and TEA1530AP) can be used in ﬁxed

frequency converter designs for low voltage, high current applications. At low power

(standby) levels, the system operates in cycle skipping mode which minimizes the

switching losses during standby.

The proprietary high voltage BCD800 process makes direct start-up possible from the

rectiﬁed universal mains voltage in an effective and green way. A second low voltage

BICMOS IC is used for accurate, high speed protection functions and control.

The TEA1530(A) enables highly efﬁcient and reliable supplies to be designed easily.

The TEA1530(A) can operate in multi modes; see Figure 4.

Because of the ﬁxed frequency mode, the internal oscillator determines the start of the

next converter stroke.

GreenChip II SMPS control IC

7.1 Start-up, mains enabling operation level and undervoltage lockout

Refer to Figure 8 and Figure 9. Initially, the IC is self supplying from the rectiﬁed mains

voltage via pin DRAIN. The supply capacitor CVCC (at pin 1) is charged by the internal

start-up current source to a level of about 4 V or higher, depending on the drain voltage.

Once the drain voltage exceeds the Vmains(oper)(en) (mains-dependent operation-enabling

level), the start-up current source will continue charging capacitor CVCC (switch S1 will be

opened), see Figure 1. The IC activates the power converter as soon as the voltage on

pin VCC passes the Vstartup level. At this moment the IC supply from the high voltage pin is

stopped (green function). The IC supply is taken over by the auxiliary winding of the

ﬂyback converter.

The moment the voltage on pin VCC drops below Vth(UVLO) (undervoltage lockout), the IC

stops switching and performs a safe restart from the rectiﬁed mains voltage. In the safe

restart mode the driver output is disabled and the voltage on pin VCC is recharged via the

pin DRAIN.

7.2 Supply management

All (internal) reference voltages are derived from a temperature compensated, on-chip

band gap circuit.

7.3 Current control mode

Current control mode is used for its good line regulation behavior.

The primary current is sensed across an external resistor and compared with the internal

control voltage. The driver output is latched in the logic, preventing multiple switch-on.

The internal control voltage is inversely proportional to the voltage on the external

pin CTRL with an offset of 1.5 V. This means that a voltage range from 1 V to

approximately 1.5 V on pin CTRL will result in a pin SENSE voltage range from

0.52 V to 25 mV (a high external control voltage results in a low duty cycle).

7.4 Oscillator

The ﬁxed frequency of the oscillator is set by an internal current source and capacitor.

7.5 Cycle skipping

At very low power levels, a cycle skipping mode activates. An internal control voltage

(Vsense(max)) lower than 25 mV will inhibit switch-on of the external power MOSFET until

this voltage increases to a higher value; see Figure 5.

7.6 Continuous Conduction Mode (CCM)

The IC operates in Fixed Frequency Continuous Conduction Mode (FF CCM). Pin DRAIN

should be connected to the high voltage rectiﬁed mains VI; see Figure 8.

7.7 OverCurrent Protection (OCP)

The primary peak current in the transformer is measured accurately cycle-by-cycle using

the external sense resistor Rsense. The OCP circuit limits the voltage on pin SENSE to an

internal level equal to 1.5 V −VCTRL (see also Section 7.3). The OCP detection is

suppressed during the leading edge blanking period, tleb to prevent false triggering caused

by the switch-on spikes.

7.8 Control pin protection

If pin CTRL becomes open-circuit or is disconnected, a fault condition is assumed and the

converter will stop switching immediately. Operation recommences when the fault

condition is removed.

7.9 Adjustable slope compensation

A slope compensation function has been added at pin CTRL; see Figure 6. The slope

compensation function prevents subharmonic oscillation in CCM at duty cycles over 50 %.

The CTRL voltage is modulated by sourcing a (non-constant) current out of pin CTRL and

by adding externally a series resistor Rslopecomp. This increases the CTRL voltage

proportionally with the on-time, which therefore limits the OCP level. A longer on-time

results in a higher CTRL voltage, this increase in CTRL voltage will decrease the on-time.

Slope compensation can be adjusted by changing the value of Rslopecomp. Slope

compensation prevents modulation of the on-time (duty cycle) while operating in FF CCM.

A possible drawback of subharmonic oscillation can be output voltage ripple.

NXP Semiconductors TEA1530T/AT/AP

GreenChip II SMPS control IC

7.10 Minimum and maximum on-time

The minimum on-time of the SMPS is determined by the LEB time (typically 400 ns). The

IC limits the maximum on-time by limiting the driver duty cycle to 70 %. So the maximum

on-time is correlated to the oscillator time which results in an accurate limit of the

minimum input voltage of the ﬂyback converter.

7.11 PROTECT and timing input

The PROTECT input (pin 3) is a multipurpose, high-impedance input, which can be used

to switch off the IC and create a relatively long timing function. As soon as the voltage on

this pin rises above 2.5 V, switching stops immediately. For the timing function, a current of

typically 50 µA ﬂows out of pin PROTECT and charges an external capacitor until the

activation level of 2.5 V is reached. This current source is only activated when the

converter is not in regulation, which is detected by the voltage on pin CTRL

(VCTRL < 0.63 V). A (small) discharge current is also implemented to ensure that the

capacitor is not charged, for example, by spikes. An internal MOSFET switch is added to

discharge the external capacitor and ensures a deﬁned start situation. For the

TEA1530AP and TEA1530AT the voltage on pin CTRL determines whether the IC enters

latched protection mode or safe restart protection mode:

•When the voltage on pin CTRL is below 0.63 V, the IC is assumed to be out of

regulation (e.g. the control loop is open). In this case activating pin PROTECT

(VPROTECT > 2.5 V) will cause the converter to stop switching. Once VCC drops below

Vth(UVLO), capacitor CVCC will be recharged and the supply will restart. This cycle will

be repeated until the fault condition is removed (safe restart mode).

•When the voltage on pin CTRL is above 0.63 V, the output is assumed to be in

regulation. In this case activating pin PROTECT (VPROTECT > 2.5 V), by external

means, will activate the latch protection of the IC. The voltage on pin VCC will cycle

between Vstartup and Vth(UVLO), but the IC will not start switching again until the latch

protection is reset. The latch is reset as soon as VCC drops below 4.5 V (typical value)

(this only occurs when the mains has been disconnected). The internal

overtemperature protection will also trigger this latch; see also Figure 1.

For the TEA1530T the IC always enters the latched mode protection independent of the

voltage on pin CTRL.

A voltage higher than 3 V on pin PROTECT will always latch the IC. This is independent of

the state of the IC.

7.12 OverTemperature Protection (OTP)

The IC provides accurate OTP. The IC stops switching when the junction temperature

exceeds the thermal shutdown temperature. When VCC drops to Vth(UVLO), capacitor CVCC

is recharged to the Vstartup level, however, switching will not restart. Subsequently, VCC will

drop again to Vth(UVLO).

Operation only recommences when VCC drops below a level of about 4.5 V, typically when

the mains voltage is disconnected for a short period.

7.13 Soft start-up (pin SENSE)

To prevent transformer rattle at start-up or during hiccup, the transformer peak current is

slowly increased by the soft start function. This can be achieved by inserting a resistor

and a capacitor between pin SENSE (pin 5) and sense resistor Rsense. An internal current

source charges the capacitor to VSENSE =I

startup(soft) ×Rss (about 0.5 V maximum).

The start level and the time constant of the increasing primary current level can be

adjusted externally by changing the values of Rss and Css.

The charging current Istartup(soft) will ﬂow as long as the voltage on pin SENSE is

below approximately 0.5 V. If the voltage on pin SENSE exceeds 0.5 V, the soft start

current source will start limiting current Istartup(soft).AtV

startup, the Istartup(soft) current source

is completely switched off, see Figure 7.

Since the soft start current Istartup(soft) is supplied from pin DRAIN, the Rss value will not

affect VCC current during start-up.

7.14 Driver

The driver circuit to the gate of the power MOSFET has a current sourcing capability of

typically 150 mA and a current sink capability of typically, 500 mA at VCC = 9.5 V. At

VCC = 15 V, the current sourcing capability is typically 250 mA and the current sink

capability typically 0.7 A. This permits fast turning on and off of the power MOSFET for

efﬁcient operation.

A low driver source current has been chosen to limit the ∆V/∆t at switch-on. This reduces

ElectroMagnetic Interference (EMI) and also limits the current spikes across Rsense.

11. Application information

A converter with the TEA1530(A) consists of an input ﬁlter, a transformer with a third

winding (auxiliary), and an output stage with a feedback circuit.

Capacitor CVCC buffers the IC supply voltage, which is powered via the internal current

source, that is connected to the rectiﬁed mains, during start-up and via the auxiliary

winding during operation.

A sense resistor Rsense converts the primary current into a voltage at pin SENSE. The

value of Rsense deﬁnes the maximum primary peak current.

Figure 8 shows a typical CCM ﬂyback conﬁguration. Pin PROTECT is used in this

example for external overtemperature protection and open loop or output short circuit

protection.

(1) Pin PROTECT is used in this example for external OTP and open loop or output short circuit

protection. Slope compensation is determined by the value of Rslopecomp.
