A7211

AiT Semiconductor Inc. www.ait-ic.com A7211 1A SYNCHRONOUS STEP-DOWN CONVERTER UNIQUE TSOT23-6 PACKAGED 5.5V TO 18V INPUT DESCRIPTION The A7211 is a current mode synchronous buck converter with integrated high side and low side power MOSFETS, and has excellent transient load and line regulation. It enables the device to adopt to both low ESR output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The A7211 operates from 5.5V to 18V VIN input, and the output voltage can be programmed between 0.81V to 14V with 1A output current, and +/-2% high accuracy output voltage. Due to 125mΩ (High side) and 70mΩ (Low side) integrated FETs, the A7211 works in high efficiency (up to 91% @12V Input, 5.0V output). The A7211 is available in TSOT-26 packages.
