Description
The SSC3S932 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 automatic dead time adjustment and the
capacitive mode detection. The product achieves high
efficiency, low noise, and high cost-effective power
supply systems with few external components.
*SMZ is the soft-switched multi-resonant zero current
switch, and is achieved soft switching operation during
all switching periods.
