Actual Size
The BPH is a revoluꢁonary, micro-sized, drop-in switching power supply
module. It contains patented technology with unique features that
provide soluꢁons for a wide range of applicaꢁons, including low power
wireless and many other intelligent control devices. The patented SMPS
topology is totally different from any other:

Small Size—0.55in3 [9.0cm3]
It's Quiet: Switching is synchronized and occurs only 10% of the ꢁme, so
there is very liꢂle 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 communicaꢁon in low power wireless
applicaꢁons.
Low no-load input power <30mW
Constant power mode, not current limit
3000 VAC Isolaꢁon

Meets UL/CSA and EN Product Safety (ITE)
It's Powerful: No power de-raꢁng across the full wide temperature range.
No current limit design margin needed when selecꢁng a module. Charge
large super caps faster than any regular SMPS with twice the power raꢁng.
Bias Power AC/DC power supplies are available with two
different types of outputs to fit your applicaꢁons…
It's Green: High efficiency with ultra low standby power and very liꢂle self
generated heat make it ideal for intelligent devices such as smart-sensors,
smart-meters, smart-lighꢁng, smart-grid, M2M or IoT , and any other control
applicaꢁons.
The characterisꢁcs of the main (Vo) and auxiliary (Vr) outputs
are different and each has applicaꢁon-speciꢀc beneꢀts which
can provide high value to the system designer:
Vo is a voltage-regulated output which has a constant power
mode instead of a convenꢁonal current limit. This output is
best suited as a source for isolated DC uꢁlity power, which may
be used directly or post-regulated with either a linear regulator
or a DC/DC converter. Vo is self protecꢁng, cannot be over-
loaded and can be shorted indefinitely. So unlike design-your-
own, or parꢁally complete modules where signiꢀcant 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 regulaꢁon to constant power along with the
wide range of product raꢁngs allows the designer to select a
supply ꢁghtly matched to the design load.

For Vo = 14V, Ir out 28mA max, Io+Ir ≤ 36mA*
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 addiꢁon, Vr is supplied internally by Vo. This means that any
capacitance added to Vo can increase the hold-up ꢁme of Vr as
well.
