DESCRIPTION/ORDERING

INFORMATION

Integrated Insulated Gated BiPolar Transistor

(IGBT) Driver

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

High Efficiency

Programmable Peak Current, 0.9 A ~ 1.8 A

Input Voltage of 1.6 V to 12 V

Optimized Control Loop for Fast Charge Time

Isolate IGBT VCC from VCC

Output Voltage Feedback From Primary Side

application. Additional advantages are

charging time and high efficiency from an optimized

pulse width modulation (PWM) control algorithm.
