Overview
® 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.
