Original PFC PWM IC SSC3S902 SOP-18 New Sanken

The SSC3S900 series are SMZ-driven controller ICs designed for LLC current-resonant switching power supplies, incorporating a floating drive circuit that drives a high-side power MOSFET.
And their functions include: Standby Mode Switching Function, Overload Protection with input voltage compensation, Automatic Dead Time Adjustment, and Capacitive Mode Detection.
These functionally-rich products enable power supply systems to be high efficient and low noise with only a few external components, resulting in downsizing and high cost-effectiveness.
