uP9616R中文资料3.3A Charger Interface, Wide Input Sensorless CC/CV Synchronous-Rectified Buck Converter for QC2.0/QC3.0/PE+1.1/PE+2.0 And FCP数据手册uPI(UBIQ)规格书

描述 Description

The uP9616R 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 3.3A output current for chargerinterface and a wide input voltage range from 8V to 32V. Itoperates in either CV (Constant Output Voltage) mode orCC (Constant Output Current) mode and provides a currentlimitation function. The uP9616R has a constant outputvoltage 5.2V/9V/12V for Qualcomm® Quick ChargeTM 3.0/2.0(QC2.0/QC3.0) that is detected from D+ and D- line andautomatically detects whether a connected Powered Device(PD) is Quick Charge (QC2.0/QC3.0) capable beforeenabling output voltage adjustment. If a PD not compliantto Quick Charge (QC2.0/QC3.0) is detected, the uP9616Rdisables output voltage adjustment to ensure safe operationwith legacy 5.2V only USB PDs.

uP9616R is a USB secondary side fast-charging converter,supporting Qualcomm® Quick ChargeTM 3.0 (QC 3.0) HighVoltage Dedicated Charging Port (HVDCP) Class Aspecification.

uP9616R allows for selection of the output voltage of anAC/DC USB adapter based on commands from the PortableDevice (PD) being powered. Selecting a higher chargingvoltage will reduce the charging current for a given powerlevel resulting in reduced IR drops and increased systemefficiency. Another advantage of QC3.0 is a decreasedbattery charging time and a reduced PD system cost thanksto the ability to select an optimum charging voltage. Thiseliminates the need for costly DC/DC converters within thePD. The USB-bus voltage can be controlled in discreetsteps from 3.6 V up to 12.1V. The output current is limitednot to exceed maximum allowable power level.

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 savingVDFN6x5-8L and VDFN5x6-10L packages.
