RT6373A Datasheet Buck Converter

Manufacturer: Richtek

Overview: RT6373A/B 17V Input, 3A, ACOT® Buck Converter with Both FETs OC Protection.

General Description

The RT6373A/B is a simple, easy-to-use, 3A synchronous step-down DC-DC converter with an input supply voltage range of 4.5V to 17V.

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

The RT6373A/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.

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 Features.
  • 3A Converter Integrated 95m and 50m FETs.
  • Input Supply Voltage Range : 4.5V to 17V.
  • Output Voltage Range : 0.6V to 7V.
  • Advanced Constant On-Time (ACOT® ) Control.
  • Ultrafast Transien.
