AS3729B

8A Power Stage

The AS3729B is a companion power stage, intended to be used

with AS372x products.

It cannot be used without a DC/DC controller. It contains the

power FETs for 2 phases and is capable to handle output

currents of 4A per phase.

Ordering Information and Content Guide appear at end of
