Original PFC PWM IC SSC3S910 SOP-18 New Sanken

The SSC3S910 is a controller with SMZ* method for LLC current resonant switching power supplies, incorporating a floating drive circuit for a high-side power MOSFET. The product includes useful functions such as the Standby Function, the Overload Protection with input voltage compensation, the Automatic Dead Time Adjustment, and the Capacitive Mode Detection. 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, achieved soft switching operation during all switching periods.
