Diodes Incorporated AP72200 | Demoboard AP72200-EVM

High Efficiency Synchronous DC/DC Buck-Boost Converter

Overview

TopologyBuck-Boost Converter
Input voltage2.3-5.5 V
Switching frequency2100-2900 kHz
Output 13.4 V / 2 A
IC revision1-2

Description

The AP72200 is a high current synchronousbuck-boost converter providing highefficiency, excellent transient response andhigh DC output accuracy. The targetedapplications are smartphones, tablets, andother handheld devices. The AP72200utilizes a four switches H-bridgeconfiguration to support buck and boostoperation. The buck-boost provides at least2A output current.The current control scheme handles wideinput/output voltage ratios and provides lowexternal component count with outstandingperformance in line/load transient responseand seamless transition between buck andboost modes.
