Analog Devices ADP1034

Description

The ADP1034 is high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regulator, an inverting buck boost dc-to-dc regulator, and a buck dc-todc regulator, providing three isolated power rails. The ADP1034 includes four high speed serial peripheral interface (SPI) isolation channels and three general-purpose isolators for channel to channel applications where low power dissipation and small solution size are required.

Features
