Datasheets PDF

General Description

The uP9601T is a high-efficiency synchronous-rectified buck converter with an internal power switch. With internal low RDS(ON) switches, the high-efficiency buck converter is capable of delivering up to 3.0A output current for charger interface and a wide input voltage range from 8.0V to 32V. It operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode, and provides a current limitation function. The uP9601T is constant output voltage 5.1V for car charger application.

Other features for the buck converter include internal softstart, adjustable external CC (Constant Output current) limit setting, chip enable, built-in fixed and adjustable linecompensation, short circuit protection, VIN/VOUT over voltage protection and over temperature protection. It is available in a space saving PSOP-8L package.
