RT5753B - 6V Synchronous Step-Down Converter

This page provides the datasheet information for the RT5753B, a member of the RT5753A 6V Synchronous Step-Down Converter family.

Description

The RT5753A/B/C/D is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V to 6V.

Features

  • cycle-by-cycle current limit protection which prevents 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, over-voltage protection (RT5753AL/BL/CL/DL) and over-temperature protection to provide safe and smooth operation in all operating conditions. Features.
  • Input Voltage Range from 2.

® RT5753A/B/C/D 3A, 1.2MHz, 6V Synchronous Step-Down Converter In WDFN-8L 2x2 General Description The RT5753A/B/C/D is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range from 2.5V 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-8L 2x2 and WDFN-8SL 2x2 packages. The RT5753A/B/C/D 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 RT5753A/C operates in automatic PSM that maintains high efficiency during light load operation.
