LLC Current-Resonant Off-Line Switching Controller

SSC3S931

Data Sheet

Description

Package

The SSC3S931 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.

SOP18

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.
