Overview
The ADP1032ACPZ-4-R7 is a high-performance, isolated micropower management unit (PMU) developed by Analog Devices Inc. This device integrates an isolated flyback regulator and a dc-to-dc buck regulator, providing two isolated power rails. It also includes four high-speed serial peripheral interface (SPI) isolation channels and three general-purpose isolators, making it ideal for applications requiring low power dissipation and a small solution size. The regulators operate at default switching frequencies of 250 kHz for the flyback and 125 kHz for the buck, with the option to be driven by an external oscillator in the range of 350 kHz to 750 kHz to enhance noise filtering in sensitive applications.
