RT6373A, Buck Converter

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 (

RT6373A 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
