Data and power isolation GENERAL DESCRIPTION
The ADP1032 is a high performance, isolated micropower
management unit (PMU) that combines an isolated flyback and a
dc-to-dc regulator providing two isolated power rails. Additionally,
the ADP1032 contains 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 is required. Operating over an input
voltage range of 4.5 V to 60 V, the ADP1032 generates isolated
output voltages of 6 V to 28 V (adjustable version) or 24 V
(fixed version) for VOUT1, and factory programmable voltages
of 5.15 V, 5.0 V, or 3.3 V for VOUT2.
By default, the ADP1032 flyback regulator operates at a 250 kHz
switching frequency, and the buck regulator operates at 125 kHz.
