2.3V TO 5.5V INPUT, 2A SYNCHRONOUS BUCK CONVERTER

Overview

TopologyBuck Converter
Input voltage2.3-5.5 V
Output 13.6 V / 1 A
IC revision1

Description

The AP61202 is a 1A, synchronous buck converter with an input voltage range of 2.3V to 5.5V and fully integrates a 120mΩ high-side power MOSFET and an 80mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.The AP61202 device is easily used by minimizing the external component count due to its adoption of constant on-time (COT) control to achieve fast transient responses, ease loop stabilization, and low output voltage ripple. Moreover, AP61202 also features force PWM mode control through EN pin.
