uP9601数据手册uPI(UBIQ)中文资料规格书

描述 Description

The uP9601 is a high-efficiency synchronous-rectified buckconverter with an internal power switch. With internal lowRDS(ON) switches, the high-efficiency buck converter iscapable of delivering up to 3.0A output current for chargerinterface and a wide input voltage range from 8.0V to 29V.It operates in either CV (Constant Output Voltage) modeor CC (Constant Output Current) mode, and provides acurrent limitation function. The uP9601 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 space saving PSOP-8L and VDFN6X5-8Lpackages.
