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
Ordering Information
The uP9616Q 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 3.3A output 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 uP9616Q has a constant output
voltage 5.2V/9V/12V for Qualcomm

3.0/
2.0(QC2.0/QC3.0) that is detected from D+ and D- line and
automatically detects whether a connected Powered Device
(PD) is Quick Charge (QC2.0/QC3.0) capable before
enabling output voltage adjustment. If a PD not compliant
to Quick Charge (QC2.0/QC3.0) is detected, the uP9616Q
disables output voltage adjustment to ensure safe operation
with legacy 5.2V only USB PDs.
uP9616Q is a USB secondary side fast-charging converter,
supporting Qualcomm

3.0 (QC 3.0) High
Voltage Dedicated Charging Port (HVDCP) Class A
specification.
uP9616Q 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 PD system cost thanks
to the ability to select an optimum charging voltage. This
eliminates the need for costly DC/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.
Other features for the buck converter include internal soft-
start, adjustable external CC (Constant Output Current)
limit setting, built-in fixed line-compensation, short circuit
protection, VIN/VOUT over voltage protection, and over
temperature protection. It is available in a space-saving
VDFN6x5-8L package.
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.
