DESCRIPTION
This device offers a complete solution for charging a
photo flash capacitor from battery input, and sub-
sequently discharging the capacitor to the xenon
tube. The device has an integrated power switch,
IGBT driver, and control logic blocks for charge
applications. Compared with discreet solutions, the
device significantly reduces the component count,
shrinks the solution size, and eases design com-
plexity. Additional advantages are fast charging time
and high efficiency due to the optimized PWM control
algorithm.
