Description

The SSC3S937 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 IC includes useful functions such

as standby function, automatic dead time adjustment,

and capacitive mode detection. The IC achieves high

efficiency, low noise and high cost-effective power

supply systems with few external components.

*SMZ: Soft-switched Multi-resonant Zero Current

switch, achieved soft switching operation during all

switching periods.
