General Description

The A8672 is a synchronous buck converter capable of delivering up to 8 A.

The A8672 utilizes valley current mode control, allowing very short on-times to be achieved.

This makes it ideal for applications that require very low output voltages relative to the input voltage, combined with high switching frequencies.

Overview

A8672 Fixed Frequency High Current Synchronous Buck Regulator with Fault Warnings and Power.

Key Features

  • High efficiency integrated FETs optimized for lower duty cycle voltage conversion: 27 mΩ high side, 12 mΩ low side.
