A7220 - 2A SYNCHRONOUS STEP-DOWN CONVERTER

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.

Features

  • 2A Output Current.
  • High Efficient Integrated FETs Optimized for portable.

AiT Semiconductor Inc. www.ait-ic.com   A7220 DC-DC CONVERTER BUCK (STEP-DOWN) 4.3V TO 18V INPUT, 2A SYNCHRONOUS 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% @12V Input, 3.3V output) The A7220 is available in SOP8 Package.
