The ADP1876 is a 600 kHz dual output synchronous buck PWM controller with linear regulator from Analog Devices. It features a wide input range (2.75 V to 20 V), high output current (more than 25 A), 180º phase shift, etc.
The ADP1876 is a dual‑output synchronous buck PWM controller operating at a fixed 600 kHz frequency. It includes an integrated 1.5 V linear regulator capable of 150 mA, a wide input range of 2.75 V to 20 V, and each channel can deliver over 25 A of output current. The controller offers 180° phase‑shifted outputs to reduce input ripple and features programmable soft‑start, slope‑compensation, and over‑current protection.
The datasheet contains detailed functional block diagrams, pin configurations, absolute maximum ratings, electrical specifications, typical performance curves, and design guidelines such as PCB layout, component selection, and loop compensation. Application notes and ordering information are also provided.
