Description
The SSC9522S is a controller IC (SMZ* method) for
half-bridge resonant type power supply, incorporating a
floating drive circuit for the high-side power MOSFET
drive.
The product achieves high efficiency, low noise and
high cost-performance power supply systems with few
external components.
*SMZ; Soft-switched Multi-resonant Zero Current
switch (All switching periods work with soft switching
operation.)
