The BPSX is a revolutionary, micro-sized, drop-in switching power supply

module.

It contains patented technology with unique features that

provide solutions for a wide range of applications, including low power

wireless and many other intelligent control devices. The patented SMPS

topology is totally different from any other:

It's Quiet: Switching is synchronized and occurs only 10% of the time, so

there is very little EMI / EMC interference with other circuits. This means no

extra filtering or shielding is needed, helping to achieve longer transmission

range with more reliable data communication in low power wireless

applications.

It's Powerful: No power de-rating across the full wide temperature range.

No current limit design margin needed when selecting a module. Charge

large super caps faster than any regular SMPS with twice the power rating.

It's Green: High efficiency with ultra low standby power and very little self

generated heat make it ideal for intelligent devices such as smart-sensors,

smart-meters, smart-lighting, smart-grid, M2M or IoT , and any other control

applications.

Bias Power AC/DC power supplies are available with two

different types of outputs to fit your applications…

The characteristics of the main (Vo) and auxiliary (Vr) outputs

are different and each has application-specific benefits which

can provide high value to the system designer:

Vo is a voltage-regulated output which has a constant power

mode instead of a conventional current limit. This output is

best suited as a source for isolated DC utility power, which may

be used directly or post-regulated with either a linear regulator

or a DC/DC converter. Vo is self protecting, cannot be over-

loaded and can be shorted indefinitely. So unlike design-your-

own, or partially complete modules where significant design

margin is required to stay far away from current limit, there is

no need to oversize a Bias Power supply. The graceful transi-

tion from voltage regulation to constant power along with the

wide range of product ratings allows the designer to select a

supply tightly 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, tightly-regulated supply.

In addition, Vr is supplied internally by Vo. This means that any

capacitance added to Vo can increase the hold-up time of Vr as

well.

*Note: maximum currents specified for constant voltage range

only. See V-I curve on page 2 for Vo in constant power range.
