A7220 Datasheet - AiT Semiconductor

A7220 2A SYNCHRONOUS STEP-DOWN CONVERTER

The A7220 is a current mode synchronous buck converter, and has a proprietary W-mode™® Gm curvature circuit that enables fast transient response, enables the device to adopt to both low ESR output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The A7220 operates from 4.3.
