RT5761B - Buck Converter

This page provides the datasheet information for the RT5761B, a member of the RT5761A Buck Converter family.

Datasheet Summary

Description

The RT5761A/B is a simple, easy-to-use, 1A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V.

The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a UDFN-6L 1.4x1 package.

Features

cycle-by-cycle current limit protection and prevent the device from the catastrophic damage in output short circuit, over current or inductor saturation. A built-in soft-start function prevents inrush current during start-up. The device also includes input under-voltage lockout, output under-voltage protection, and over-temperature protection to provide safe and smooth operation in all operating conditions. Features.
Input Voltage Range from 2.5V to 6V.
Integrated 120m and 80m FETs.

RT5761A/B 6V 1A, ACOT® Buck Converter in Thin UDFN-6L 1.4x1 Package General Description The RT5761A/B is a simple, easy-to-use, 1A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V. The device build-in an accurate 0.6V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency in a UDFN-6L 1.4x1 package. The RT5761A/B adopts Advanced Constant On-Time (ACOT® ) control architecture to provide an ultrafast transient response with few external components and to operate in nearly constant switching frequency over the line, load, and output voltage range. The RT5761A operate in automatic PSM that maintain high efficiency during light load operation.
