2A, 18V, High-Efficiency

Synchronous-Rectified Buck Converter

Features

General Description

The uP1724 is a high-efficiency synchronous-rectified

buck converter with internal power switch. With internal

low R_DS(ON)switches, the high-efficiency buck converter is

capable of delivering 2A output current over a wide input

voltage range from 4.5V to 18V. The output voltage is

adjustable from 0.8V to 15V by a voltage divider. Other

features for the buck converter include adjust soft-start,

chip enable, over-voltage, under-voltage, over-

temperature and over-current protections. It is available

in a space saving PSOP-8L package.
