Analog Devices ADP1877 Dual Output Synchronous Buck PWM Controller Datasheet
The ADP1877 is a Flex‑Mode™ dual‑channel step‑down switching controller that integrates MOSFET drivers and boost diodes. Its two PWM outputs are phase‑shifted 180°, reducing input RMS current and required input capacitance.
The device operates from 2.75 V to 14.5 V input, delivers up to 25 A per channel, and offers programmable frequency, soft‑start, over‑voltage, over‑current and thermal protection features. It is supplied in a 32‑lead 5 mm × 5 mm LFCSP package and is suited for set‑top boxes, printers, communication infrastructure, and industrial instrumentation. This manual is written in Chinese.
