High Efficiency, Low noise, Automatic Dead Time Adjustment Control IC for Half-Bridge LLC Off-line Switching Regulators SSC9522S General Description The SSC9522S is a controller IC (SMZ* method) for half-bridge resonant type power supply, incorporating a floating drive circuit for High-side MOSFET drive. *SMZ = Soft-switched Multi-resonant Zero Current switch, all switching periods work with soft switching operation. The IC is suitable for high performance power supply system with small size, high efficiency and low noise, because for various power supply specifications, more effective and easier design works are achievable with effective functions as the Automatic Dead Time Adjustment, the Uncontrollable Operation Detection and so on.
