SSC3S932
Package：SOP18
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.
