LLC Current-Resonant Off-Line Switching Controller  
SSC3S921  
Data Sheet  
Description  
Package  
The SSC3S921 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.  
SOP18  
The IC achieves high efficiency, low noise and high  
cost-performance power supply systems with few  
external components.  
*SMZ: Soft-switched Multi-resonant Zero Current  
switch, achieved soft switching operation during all  
switching periods.  
Not to scale  
Features  
Standby Mode Change Function  
Output Power at Light Load: PO = 125 mW  
(PIN = 0.27 W, as a reference with discharge resistor  
of 1MΩ for across the line capacitor)  
Burst operation in standby mode  
Soft-on/Soft-off function: reduces audible noise  
PFC IC ON/OFF Function: In standby operation, the IC  
turns off PFC IC.  
Applications  
Switching power supplies for electronic devices such as:  
Digital appliances: LCD television and so forth  
Office automation (OA) equipment: server, multi-  
function printer, and so forth  
Soft-start Function  
Capacitive Mode Detection Function  
Reset Detection Function  
Industrial apparatus  
Communication facilities  
Automatic Dead Time Adjustment Function  
Input Electrolytic Capacitor Discharge Function  
Protections  
Brown-In and Brown-Out Function:
