INTEGRATED PHOTO FLASH CHARGER AND IGBT DRIVER
Digital Still Cameras (DSC)
Highly Integrated Solution to Reduce
Components
Optical Film Cameras
Mobile Phones With Camera
Integrated 50-V Power Switch,
R(ON) = 200 m Typical
PDAs With Camera
Integrated IGBT Driver
High Efficiency
This device offers a complete solution for charging a
Programmable Peak Current, 0.95 A ~ 1.8 A
photo flash capacitor from battery input, and sub-
Input Voltage of 1.8 V to 12 V
sequently discharging the capacitor to the xenon
Optimized Control Loop for Fast Charge Time
tube. The device has an integrated power switch,
IGBT driver, and control logic blocks for charge
Sensing All Trigger From Primary Side
applications. Compared with discrete solutions, the
10-Pin MSOP/16-Pin QFN Package
device significantly reduces the component count,
Protection
shrinks the solution size, and eases design com-
– MAX On Time
plexity. Additional advantages are fast charging time
and high efficiency due to the optimized PWM control
– Over VDS Shutdown
algorithm.
– Thermal Monitor
Other provisions of the device includes four options
for
determining
a
different
target
voltage,
programmable peak current, thermal disable monitor,
input signal for charge enable, flash enable, and an
output signal for charge completion status.
