RT9598
RT9598 is MOSFET Integrated Smart Photoflash Capacitor Charger manufactured by Richtek.
Description
The RT9598 is a plete photoflash module solution for digital and film cameras. It is targeted for applications that use 2 to 4 AA batteries or 1 to 2 Lithium-Ion batteries. The RT9598 adopts Flyback topology which uses constant primary peak current and zero secondary valley current to charge photoflash capacitor quickly and efficiently. The built-in 55V MOSFET allows flexibility in transformer design and simplifies the PCB layout. The RT9598 also integrates an IGBT driver for igniting photoflash tube. Only a few external ponents are required, which greatly reduces the PCB space and cost. The RT9598 is available in the WDFN-8L 2x2 package.
