Integrated Voltage Reference
PDAs With Camera
Integrated 50-V Power Switch,
Integrated IGBT Driver
High Efficiency
This device offers a complete solution for charging a
Programmable Peak Current, 0.9 A ~ 1.8 A
photo
flash
capacitor
from
battery
input,
and
Input Battery Voltage of 1.6 V to 12 V
subsequently discharging the capacitor to a xenon
Optimized Control Loop for Fast Charge Time
flash tube. The device has an integrated voltage
reference, power switch, IGBT driver, and control
Output Voltage Feedback From Primary Side
logic blocks for charging applications and driving
16-Pin QFN Package
IGBT applications. Compared with discrete solutions,
Protection
this device reduces the component count, shrinks the
solution size, and eases designs for xenon tube
– MAX On Time
applications.
Additional
advantages
are
a
fast
– MAX Off Time
charging time and high efficiency from an optimized
– Overcurrent Shutdown to Monitor VDS at the
PWM control algorithm.
SW pin (OVDS)
Other provisions of the device includes sensing the
– Thermal Disable
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.
