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

Overview

TopologyBuck Converter
Input voltage2.3-5.5 V
Output 13 A
IC revisionJanuary 2021

Description

The AP61300/AP61302 is a 3A, synchronous buck converter with a wide input voltage range of 2.4V to 5.5V. The device fully integrates a 70mΩ high-side power MOSFET and a 50mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.The AP61300/AP61302 device is easily used by minimizing the external component count due to its adoption of Constant On-Time (COT) control to achieve fast transient response, easy loop stabilization, and low output voltage ripple. The device is available in a SOT563 package.
