Wide Input Voltage  
VBAT = 1.4 V to 12 V  
VCC = 2.7 V to 5.5 V  
The TPS65563 offers a complete solution for a  
charging photo flash capacitor and flashing xenon  
tube with insulated gate bipolar transfer (IGBT) driver.  
This device has an integrated voltage reference,  
power switch (SW), comparators for peak current  
Integrated 50-V Power Switch With Lower RON  
Programmable Peak Current at Primary Side  
From 0.5 A to 2 A  
detection/power  
SW  
turnon  
detection/charge  
complete detection, IGBT driver and control logics for  
charging applications/driving IGBT applications.  
Optimized Switch ON/OFF Control for Fast  
Charging  
Compared with discrete solutions, this device reduces  
the component count, shrinks the total solution size,  
and erases the difficulty of design for xenon tube  
application.  
Charge Complete Detection at Primary Side  
With High Accuracy  
Integrated IGBT Driver  
3-mm × 3-mm, 16-Pin QFN Package  
Protection  
Additional advantages are a fast charging time and  
high efficiency since this device has an optimized  
pulse width modulation (PWM) control algorithm for  
photo flash charging. Also this device has high  
accuracy for peak current detection and for charge  
completion detection. The distribution of charging  
time is smaller.  
Overcurrent Protection (OCP)  
Thermal Shutdown (TSD)  
APPLICATIONS  
Digital Still Cameras  
Optical Film Cameras  
Digital Video Camcorders  
Cell Phones  
Other provisions of the device include sensing the  
output voltage at the primary side, programmable  
peak current at the primary side, protection features  
(thermal shutdown and overcurrent), an output pin for  
charge completion detection, input pins for charge  
enable, flash acceptable, and flash on.
