uP9616
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 uP9616 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 uP9616 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 uP9616
disables output voltage adjustment to ensure safe operation
with legacy 5.2V 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.

uP9616 allows for selection of the output voltage of anAC/
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.
