DESCRIPTION/ORDERING INFORMATION
The TPS65563A offers a complete solution for a
charging photo flash capacitor and flashing xenon
tube with an insulated gate bipolar transfer (IGBT)
driver. This device has an integrated voltage
reference, power switch (SW), comparators for peak
current detection/power SW turnon detection/charge
complete detection, an IGBT driver, and control logics
for charging applications/driving IGBT applications.
Compared with discrete solutions, this device reduces
the component count, shrinks the total solution size,
and erases the difficulty of design for xenon-tube
applications.
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. In addition, this device has high
accuracy for peak current detection and for charge
completion detection. The distribution of charging
time is smaller.
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, and input pins for
charge enable, flash acceptable, and flash on.
