RAA808013 - 3A Synchronous Buck Regulator

Description

3.

.

Features

  • a PFM mode for improved efficiency at light loads. The RAA808013 adopts Constant On-Time (COT) 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 part switches at a default frequency of 1.5MHz. The RAA808013 can switch between constant on-time control and constant off-time control smoothly and can also switch between constant off-time control and 100%.
