Product Description
The CMPWR300 is a dual input regulator with V
AUX
switch ca-
pable of delivering 3.3V/500mA continuously. The output power
is provided from three independent input voltage sources on a
prioritized basis. Power is always taken in priority using the fol-
lowing order V
CC
, V
SBY
, and V
AUX
.
When V
CC
(5V) or V
SBY
is present, the device automatically en-
ables the regulator and produces a stable 3.3V output at V
OUT
.
When only V
AUX
(3.3V) is present, the device provides a low
impedance direct connection (0.12Ω typ.) from V
AUX
to V
OUT
.
All the necessary control circuitry needed to provide a smooth
and automatic transition between all three supplies has been
incorporated. This allows both V
CC
and V
SBY
to be dynamically
switched without loss of output voltage.
