ADP1053ACPZ-R7

Overview

The ADP1053ACPZ-R7 is a three-channel digital power controller from Analog Devices, designed for isolated and non-isolated DC-to-DC and AC/DC converter applications. It utilizes a voltage mode PWM architecture to provide control, monitoring, and protection for up to three independent channel outputs. The device features eight flexible PWM outputs configurable as two regulated channels with feedback control and one unregulated channel with a fixed duty cycle. Switching frequencies are individually programmable from 50 kHz to 625 kHz. It supports differential voltage sensing, fast current sensing, and synchronization between devices.

Feature Summary
