General Description
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.
