YNCHRONOUS STEP-DOWN CONVERTER WITH FAST TRANSIENT RESPONSE DESCRIPTION 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 4.3V to 18V VIN input, and the output voltage can be programmed between 0.918V to 14V with 2A output current, and +/-1.5% high accuracy output voltage. Due to 95mΩ (High side) and 90mΩ (Low side) integrated FETs, the A7220 works in high efficiency (up to 94% @1
