描述 Description

The uP9601T is a high-efficiency synchronous-rectifiedbuck converter with an internal power switch. With internallow RDS(ON) switches, the high-efficiency buck converteris capable of delivering up to 3.0A output current for chargerinterface and a wide input voltage range from 8.0V to 32V.It operates in either CV (Constant Output Voltage) modeor CC (Constant Output Current) mode, and provides acurrent limitation function. The uP9601T is constant outputvoltage 5.1V for car charger application.Other features for the buck converter include internal softstart,adjustable external CC (Constant Output current) limitsetting, chip enable, built-in fixed and adjustable linecompensation,short circuit protection, VIN/VOUT overvoltage protection and over temperature protection. It isavailable in a space saving PSOP-8L package.
