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

Quick Charge

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

Quick Charge

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.
