RT5753 - 6V Synchronous Step-Down Converter

Description

The RT5753 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.

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 undervoltage lockout, output undervoltage protection, overvoltage protection (RT5753AL/BL/CL/DL/EL/FL) and over-temperature protection to provide safe and smooth operation in all operating conditions.

® RT5753 3A, 1.2MHz, 6V Synchronous Step-Down Converter In WDFN-8L 2x2 General Description The RT5753 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 RT5753 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/E/F operates in automatic PSM that maintains high efficiency during light load operation.
