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

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

uP9616 allows for selection of the output voltage of aC/  
DC USB adapter based on commands from the Portable  
Device (PD) being powered. Selecting a higheng  
voltage will reduce the charging current for a er  
level resulting in reduced IR drops and increasem  
efficiency. Another advantage of Q.0 is a decreased  
battery charging time and a reduced Dsystem st thanks  
to the ability to select an optimum arging voge. This  
eliminates the need for costlyDC/DC vertewithin the  
PD. The USB-bus voltage can be controlled in discreet  
steps from 3.6 V up to 12.1VThe output current is limited  
not to exceed maximum allowpower level.
