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.

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. The digital isolators integrated in the ADP1032 use Analog Devices, Inc., iCoupler? chip scale transformer technology, optimized for low power and low radiated emissions. The ADP1032 is available in a 9 mm × 7 mm, 41-lead LFCSP and is rated for a ?40℃ to +125℃ operating junction temperature range.
