DESCRIPTION

High Efficiency

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.

Programmable Peak Current, 0.95 A ~ 1.8 A

Input Voltage of 1.8 V to 12 V

Optimized Control Loop for Fast Charge Time

Sensing All Trigger From Primary Side

10-Pin MSOP/16-Pin QFN Package

Protection

– MAX On Time

– Over V_DSShutdown

– Thermal Monitor

Other provisions of the device includes four options

for determining

different target voltage,

programmable peak current, thermal disable monitor,

input signal for charge enable, flash enable, and an

output signal for charge completion status.
