DESCRIPTION

This device offers a complete solution for charging a

photo flash capacitor from a battery input, and subsequently discharging the capacitor to a xenon

flash tube. The device has an integrated voltage

reference, power switch, IGBT driver, and control

logic blocks for capacitor charging applications and

driving IGBT applications. Compared with discrete

solutions, this device reduces the component count,

shrinks the solution size, and eases designs for

xenon tube applications. Additional advantages are a

fast charging time and high efficiency from an

optimized 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.
