THEORY OF OPERATION

The ADP1032 is a high performance, isolated micro PMU that

combines an isolated flyback regulator and a buck regulator,

providing two isolated power rails. Additionally, the ADP1032

includes seven low power digital isolators in a 41-lead LFCSP

package for channel to channel isolated applications where

power dissipation and board space are at a premium.
