RT6274D - Buck Converter

Download the RT6274D datasheet PDF. This datasheet also covers the RT6274C variant, as both devices belong to the same buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The RT6274C/D is a simple, easy-to-use, 3.5A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 18V.

The device possesses an accurate 0.765V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency.

Key Features

  • cycle-by-cycle current limit protection to prevent the device from the catastrophic damage in output short circuit, over-current or inductor saturation conditions. 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 (thermal shutdown) to provide safe and smooth operation in all operating conditions. The recommended junction temperature range is.
  • 40C.

RT6274C/D is a simple, easy-to-use, 3.5A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 18V. The device possesses an accurate 0.765V reference voltage and integrates low RDS(ON) power MOSFETs to achieve high efficiency. The RT6274C/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 RT6274C operates in automatic PSM that maintains high efficiency during light load operation.
