ADP2164 - Step-Down DC-to-DC Regulator

Datasheet Summary

Description

The ADP2164 is a 4 A, synchronous, step-down, dc-to-dc regulator in a compact 4 mm × 4 mm LFCSP package.

The regulator uses a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response.
