uP9602Q数据手册uPI(UBIQ)中文资料规格书

描述 Description

The uP9602 is certified by Qualcomm® and UL for QC2.0.The uP9602 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 3A output current for chargerinterface and a wide input voltage range from 8V to 29V. Itoperates in either CV (Constant Output Voltage) mode orCC (Constant Output Current) mode and provides a currentlimitation function. The uP9602 has a constant outputvoltage 5.1V/9V/12V for Quick Charge 2.0 ( QC2.0 ) thatis detected from D+ and D- line and automatically detectswhether a connected Powered Device (PD) is Quick Charge2.0 capable before enabling output voltage adjustment. If aPD not compliant to Quick Charge 2.0 is detected, theuP9602 disables output voltage adjustment to ensure safeoperation with legacy 5.1V only USB PDs.

Other features for the buck converter include internal softstart,adjustable external CC (Constant Output Current)limit setting, built-in fixed line-compensation, short circuitprotection, VIN/VOUT over voltage protection, and overtemperature protection. It is available in space savingPSOP-8L and VDFN6x5-8L packages.
