ADP5053 Datasheet Integrated Power Solution

Manufacturer: Analog Devices

General Description

The ADP5053 combines four high performance buck regulators, a supervisory circuit, a watchdog timer, and a manual reset in a 48-lead LFCSP package that meets demanding performance and board space requirements.

The device enables direct connection to high input voltages up to 15.0 V with no preregulators.

Channel 1 and Channel 2 integrate high-side power MOSFET and low-side MOSFET drivers.
