Introduction

This device is a synchronous step-down DC-DC converter with a maximum input voltage of 48V, a load current of 0.6A, housed in a 3mm×3mm SOT23-6 package. The output voltage is adjustable via an external resistive voltage divider on the feedback pin, supporting a range of 5V to 40V. The device features ultra-low quiescent current for high efficiency under light-load conditions, significantly reducing power consumption in battery-powered systems. Its wide input voltage range (8V to 48V) reduces the need for external surge suppression components, making it suitable for industrial and multi-cell battery applications. Integrated power MOSFETs, peak current mode control, and internal compensation, with a maximum output current of 0.6A, ensure excellent load and input transient response.

Features

  • Wide input voltage range: 8V to 48V
  • Adjustable output voltage range: 5V to 40V
