MOSFET Integrated Smart Photoflash Capacitor Charger
Description
RT9594A/B
MOSFET Integrated Smart Photoflash Capacitor Charger with IGBT Driver
General Description
Features
The RT9594A/B are complete photoflash module solutions for digital and film cameras.
They are targeted for applications that use 2 to 4 AA batteries or 1 to 2 lithiumion batteries.
The RT9594A/B adopt flyback topology which use constant primary peak current and zero secondary valley current to charge photoflash capacitor quickly and efficiently.
The built-in 50V MOSFET allows flexibility in transformer design and simplifies the PCB layout.
The RT9594A/B also integrate an IGBT driver for igniting photoflash tube.
Only a few external components are required, which greatly reduces the PCB space and cost.
The RT9594A/B are available in the WQFN-16L 3x3 package.
