RT5750A - Buck Converter

Datasheet Summary

Description

The RT5750A/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 TSOT-23-5 and TSOT-23-6 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.

RT5750A/B 6V 1A, ACOT® Buck Converter General Description The RT5750A/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 TSOT-23-5 and TSOT-23-6 package. The RT5750A/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 RT5750A operate in automatic PSM that maintain high efficiency during light load operation. The RT5750B operate in Forced PWM that help to meet tight voltage regulation accuracy requirements.
