General Description
The TC115 is a high-efficiency step-up DC/DC
converter for small, low input voltage or battery-
powered systems. This device has a start-up voltage
of 0.9V and a typical supply current of 80 µA. Phase
compensation and soft-start circuitry are included on-
chip. Unlike conventional PWM step-up converters,
the TC115 automatically shifts to pulse frequency
modulation (PFM) at low loads, resulting in reduced
supply current and improved efficiency.
The TC115 require s only an external di ode, an inductor
and a capacitor, while supporting typical output cur-
rents of 140 mA. Suppl y current is reduc ed to less than
0.5 µA (max) when SHDN input is brought low.
Small size, low installed cost and low supply current
make the TC115 step-up converter ideal for use in a
wide range of battery-powered systems.

4.0 DETAILED DESCRIPTION
The TC115 is a combination PFM/PWM step-up
(boost) r egulator. It is p articular ly usefu l in batte ry-pow-
ered 1, 2 and 3 cell a pplications whe re the required out-
put current is 140 mA or less, and size/cost issues are
a concern. The device operates in PWM mode when
the output load is sufficient to demand a 10% (or
greater) duty cycle. While in PWM mode, the TC115
behaves as any other PWM switching regulator to a
maximum duty cycle of 92%. At low output loads (i.e.,
output loads requiring < 10% duty cycle to support ), the
TC115 autom atical ly switc hes to p ulse fre quency mod-
ulation (PFM) operating mode with a fix ed duty cycl e of
25% (max) (17%, typical). While in PFM mode, the
inducto r is mo dulate d with individ ual fix ed wid th pul ses
only as needed to maintain output voltage. This action
reduces supply current, thereby improving power
efficiency at low output loads.
4.1 Input Power and Sensing
The TC115 is powered from the PS input, which must
be connected to the regulated output, as shown in
Figure 5-1. PS also senses output voltage for closed-
loop regulation. Start-up current is furnished through
the inductor when input vo lt a ge is initially applie d. Thi s
action starts the oscillator, causing the voltage at the
PS input to rise, bootstrapping the regulator into full
operation.
4.2 Output Diode
For best results, use a Schottky diode, such as the
MA735, 1N5817, EC10 or equivalent. Connect the
diode b etween the PS and LX pins as close to the IC as
possible. While ultra fast di odes can be used, lower effi-
ciency will result due to their higher forward voltage
drop. Ordinary rectifiers should be avoided because of
their slow recovery characteristics.
4.3 Low Power Shutdown Mode
The TC115 enters a low power shutdown mode when
SHDN is brought low. While in shutdown, the oscillator
is disabled and the internal switch is shut off. Normal
regulator operation resumes when SHDN is brought
high. SH DN may be tied to th e input sup ply if not use d.
4.4 Behavior When VIN is Greater
Than the Factory-Progr ammed
VOUT Setting
The TC115 is designed to operate as a step-up
regulator only. As such, VIN is assumed to always be
less than the factory-programmed VOUT setting (VR).
Operating the TC115 with VIN > VR causes regulating
action to be suspended (and corresponding supply
current reducti on to 9 µA, typi cal) until V IN is again less
than VR. While regulating action is suspended, VIN is
connected to VOUT through the series combination of
the indu ctor an d Schottky di ode. Care must be taken to
add the appropriate isolation (MOSFET output switch
or post LDO with shutdown) during system design if
this VIN/VOUT leakage path is problematic.
Note: Because the TC115 uses an external
diode, a leakage path between the input
voltage and the output node (through the
induc tor and di ode) exi sts while t he regu-
lator is in shut down. Care must be taken in
system design to assure the input supply
is isolated f rom th e load during sh utdown.

5.0 APPLICATIONS
5.1 Input Bypass Capacitors
Using an input bypass capacitor reduces peak current
transien ts drawn from the inp ut supply and reduce s the
switchi ng noise ge nerated by the regulato r . Th e source
impedance of the input supply determines the size of
the capacitor that should be used.
FIGURE 5-1: TC115 Typical Application.
5.2 Inductor Selection
Selecting the proper inductor value is a trade-off
between physical size and power conversion require-
ments. Lower value inductors cost less, but result in
higher ripple current and core losses. They are also
more prone to saturate since the coil current ramps to
a higher value. Larger inductor values reduce both
ripple cu rrent and core losses, but are larger in physical
size and tend to increase the start-up time slightly.
Practical inductor values, therefore, range from 50 µH
to 300 µH. Inductors with a ferrite core (or equivalent)
are recommended. For highest efficiency, use an
inductor with a series resistance less than 0.1).
The inductor value directly affects the output ripple
voltage. Equation 5-3 is derived as shown below, and
can be used to calculate an inductor value, given the
required output ripple voltage (VRIPPLE) and output
capacitor series resistance:
EQUATION 5-1:
Expressing di in terms of switch ON resistance and
time:
EQUATION 5-2:
Solving for L:
EQUATION 5-3:
Care must be taken to ensure the inductor can handle
peak switching currents, which can be several times
load currents. Exceeding rated peak current will result
in core saturation and loss of inductance. The inductor
should be selected to withstand currents greater than
IPK (Equation 5-10) without saturating.
Calculat ing the peak in ductor current is straightforward.
Inductor current consists of an AC (sawtooth) current
centered on an ave rage DC cu rrent (i.e., i nput curren t).
Equation 5-6 calculates the average DC current. Note
that minimum input voltage and maximum load current
values should be used:

ages:
EQUATION 5-5:
Solving for input current:
EQUATION 5-6:
The sawtooth current is centered on the DC current
level, swinging e qually above and below th e DC current
calculated in Equation 5-6. The peak inductor current is
the sum of the DC current plus half the ac current. Note
that minimum input voltage should be used when
calcul ati ng the ac inductor current (Equation 5 -9).
EQUATION 5-7:
EQUATION 5-8:
EQUATION 5-9:
Combining the DC current calculated in Equation 5-6,
with half the peak ac current calculated in Equation 5-9,
the peak inductor current is given by:
EQUATION 5-10:
5.3 Internal Transist or Switch
The LX pin has a typical ON resistance of 1.4.
Therefore, peak switch current is given by (VIN/1.4).
The internal transistor switch has a maximum design
rating of 350 mA. An oscillator frequency doubling cir-
cuit is an included guard against high switching cur-
rents . Should th e volt age on the LX pin rise above 1. 3V
(max) while the internal N-channel switch is ON, the
oscillator frequency automatically doubles to minimize
ON time. Although reduced, switch current still flows
becaus e the PWM remains in ope ration. Therefore, the
LX input is not internally current-limited and c are must
be taken never to exceed the 350 mA maximum limit.
Failure to observe this will result in damage to the
regulator.
5.4 Output Capacitor
The e ffe ctive se ries res istance o f the out put capac itor
directly affects the amplitude of the output voltage
ripple (The product of the p eak inductor curren t and the
ESR determines output ripple amplitude). Therefore, a
capacitor with the lowest possible ESR should be
selected. Smaller capacitors are acceptable for light
loads (or i n a pplications wh ere ripple is n ot a c on cern).
The Sprague® 595D series of tantalum capacitors are
among the smallest of all low ESR surface mount
capacitors available. Table 5-1 lists suggested
components and suppliers.
5.5 Board Layout Guidelines
As with all inductive switching regulators, the TC115
generates fast switching waveforms which radiate
noise. Interconnecting lead lengths should be
minim ized to keep stray capacitance , trace resistance
and radiated noise as low as possible. In addition, the
GND pin, input bypass capacitor and output filter
capa citor groun d leads shou ld be connected to a single
point.
