RT9595
MOSFET Integrated Smart Photoflash Capacitor Charger
with IGBT Driver
General Description
The RT9595 is a complete photoflash module solution for
digital and film cameras. It is targeted for applications that
use 2 to 3 AA batteries or 1 Lithium-Ion battery. The RT9595
adopts fly back topology which use constant primary peak
current and zero secondary valley current to charge
photoflash capacitor quickly and efficiently. The built-in
45V MOSFET allows flexibility in transformer design and
simplifies the PCB layout. The RT9595 also integrate an
IGBT driver for igniting photoflash tube. Only a few external
components are required, which greatly reduce the PCB
space and cost. The RT9595 is available in the
WDFN-10L 3x3 package.
