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 BPH 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 eciency 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.
