Bias Power AC/DC power supplies are available with two
dierent types of outputs to t your applicaons…
The characteriscs of the main (Vo) and auxiliary (Vr) outputs
are dierent and each has applicaon-specic benets which
can provide high value to the system designer:
Vo is a voltage-regulated output which has a constant power
mode instead of a convenonal current limit. This output is
best suited as a source for isolated DC ulity power, which may
be used directly or post-regulated with either a linear regulator
or a DC/DC converter. Vo is self protecng, cannot be over-
loaded and can be shorted indenitely. So unlike design-your-
own, or parally complete modules where signicant design
margin is required to stay far away from current limit, there is
no need to oversize a Bias Power supply. The graceful transi-
on from voltage regulaon to constant power along with the
wide range of product rangs allows the designer to select a
supply ghtly matched to the design load.
Vr is also a voltage-regulated output and is thermally protected
from overload. It has very low output ripple capable of driving
elements which require a low-noise, ghtly-regulated supply.
In addion, Vr is supplied internally by Vo. This means that any
capacitance added to Vo can increase the hold-up me of Vr as
well.
*Note: maximum currents specied for constant voltage range
only. See V-I curve on page 2 for Vo in constant power range.
The BPSX is a revoluonary, micro-sized, drop-in switching power supply
module. It contains patented technology with unique features that
provide soluons for a wide range of applicaons, including low power
wireless and many other intelligent control devices. The patented SMPS
topology is totally dierent from any other:
It's Quiet: Switching is synchronized and occurs only 10% of the me, so
there is very lile EMI / EMC interference with other circuits. This means no
extra ltering or shielding is needed, helping to achieve longer transmission
range with more reliable data communicaon in low power wireless
applicaons.
It's Powerful: No power de-rang across the full wide temperature range.
No current limit design margin needed when selecng a module. Charge
large super caps faster than any regular SMPS with twice the power rang.
It's Green: High eciency with ultra low standby power and very lile self
generated heat make it ideal for intelligent devices such as smart-sensors,
smart-meters, smart-lighng, smart-grid, M2M or IoT , and any other control
applicaons.
