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  
General Description  
Applications  
The uP9616S 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 3.3Aoutput current for charger  
interface and a wide input voltage range from 8V to 32V. It  
operates in either CV (Constant Output Voltage) mode or  
CC (Constant Output Current) mode and provides a current  
limitation function. The uP9616S has a constant output

2.0(QC2.0/QC3.0) that is detected fromD+ andD- line and  
automatically detects whether a connected PoweredDevice  
(PD) is Quick Charge (QC2.0/QC3.0) capable before  
enabling output voltage adjustment. If a PDnot compliant  
to Quick Charge (QC2.0/QC3.0) is detected, the uP9616S  
disables output voltage adjustment to ensure safe operation  
with legacy 5.1V only USB PDs.  
Note:  
(1) Please check the sample/production availability with  
uPI representatives.  
(2) uPI products are compatible with the current IPC/JEDEC  
J-STD-020 requirement. They are halogen-free, RoHS  
compliant and 100% matte tin (Sn) plating that are suitable  
for use in SnPb or Pb-free soldering processes.

uP9616S allows for selection of the output voltage of an  
AC/DC USB adapter based on commands from the Portable  
Device (PD) being powered. Selecting a higher charging  
voltage will reduce the charging current for a given power  
level resulting in reduced IR drops and increased system  
efficiency. Another advantage of QC3.0 is a decreased  
battery charging time and a reduced PDsystem cost thanks  
to the ability to select an optimum charging voltage. This  
eliminates the need for costlyDC/DC converters within the  
PD. The USB-bus voltage can be controlled in discreet  
steps from 3.6 V up to 12.1V. The output current is limited  
not to exceed maximum allowable power level.

limit setting, built-in fixed line-compensation, short circuit  
protection, VIN/VOUT over voltage protection, and over  
temperature protection. It is available in space saving  
VDFN6x5-8L and VDFN5x6-10L packages.
