RT5751D - Buck Converter

This page provides the datasheet information for the RT5751D, a member of the RT5751C Buck Converter family.

Datasheet Summary

Description

The RT5751C/D is a simple, easy-to-use, 1.5A synchronous step-down DC-DC converter with an input supply voltage range from 2.8V to 6V.

Features

  • cycle-by-cycle current-limit protection and prevents the device from the catastrophic damage in output short circuit, overcurrent or inductor saturation. A built-in soft-start function prevents inrush current during start-up. The device also includes input undervoltage lockout, output undervoltage protection, and over-temperature protection to provide safe and smooth operation in all operating conditions. Features.
  • Input Voltage Range from 2.8V to 6V.
  • Integrated 120m and 80m FETs.

RT5751C/D 6V 1.5A, ACOT® Buck Converter General Description The RT5751C/D is a simple, easy-to-use, 1.5A synchronous step-down DC-DC converter with an input supply voltage range from 2.8V to 6V. The device builds in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in WDFN-6L 2x2, TSOT-23-5 and TSOT-23-6 packages. The RT5751C/D adopts Advanced Constant On-Time (ACOT® ) control architecture to provide an ultrafast transient response with few external components and to operate at nearly constant switching frequency over the line, load, and output voltage range. The RT5751C operates in automatic PSM that maintains high efficiency during light load operation.
