This device offers a complete solution for charging photo flash capacitor from battery input, and subsequently discharging the capacitor to a xenon flash tube. This device has an integrated voltage reference, power switch, IGBT driver, and control logic blocks for charging applications and driving IGBT application. Compared with discreet solutions, this device reduces the component count, shrinks the solution size, and eases designs for xenon tube application. Additional advantages are a fast charging time and high efficiency from an optimized pulse width modulation (PWM) control algorithm.

Other provisions of the device includes sensing the output voltage from the primary side, programmable peak current, thermal shutdown, an output pin for charge completion, and input pins for charge enable and flash enable.
