The BPWX 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.

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.
