Figure 1.

The two regulators are phase shifted relative to each other to

reduce electromagnetic interference (EMI). The ADP1032 can

be driven by an external oscillator in the range of 350 kHz to

750 kHz to ease noise filtering in sensitive applications.

APPLICATIONS

The digital isolators integrated in the ADP1032 use Analog

Devices, Inc., iCoupler® chip scale transformer technology,

optimized for low power and low radiated emissions.

Data and power isolation

The ADP1032 is available in a 9 mm × 7 mm, 41-lead LFCSP and

is rated for a −40°C to +125°C operating junction temperature

range.

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 V_OUT1, and factory programmable voltages
