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

•
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.

•
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.
