2.3V TO 5.5V INPUT, 3A SYNCHRONOUS BUCK CONVERTER

Overview

TopologyBuck Converter
Input voltage2.3-5.5 V
Output 15 V / 3 A
IC revisionJanuary 2021

Description

The AP61302Q is a 3A, synchronous buck converter with an input voltage range of 2.3V to 5.5V and fully integrates a 120mΩ high-side power MOSFET and a 80mΩ low-side power MOSFET to provide high-efficiency step-down DC/DC conversion.The AP61302Q 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, AP61302Q also features force PWM mode control through EN pin.
