Analog Devices ADP1032 Micropower Management Units

Tuesday, 01 December, 2020 | Supplied by: Mouser Electronics

Analog Devices ADP1032 Micropower Management Units (PMUs) are high-performance, isolated devices that combine an isolated flyback and a DC-to-DC regulator providing two isolated power rails. Additionally, they contain 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.

Operating over an input voltage range of 4.5 to 60 V, the units generate isolated output voltages of 6 to 28 V (adjustable version) or 24 V (fixed version) for VOUT1. They also have factory-programmable voltages of 5.15, 5 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) and can be driven by an external oscillator in the range of 350 to 750 kHz to ease noise filtering in sensitive applications. The digital isolators integrated into the ADP1032 use Analog Devices’ iCoupler chip-scale transformer technology, optimised for low-power and low-radiated emissions.

The PMU is available in a 9 x 7 mm, 41-lead LFCSP and is rated for a -40 to +125°C operating junction temperature range.
