SSC9502
Controller IC for Current Resonant Type Switching Power Supply
with Half-Bridge Resonance, High Efficiency and Low Noise
General Descriptions
The SSC9502 is a controller IC, incorporating a floating drive circuit for half-bridge type
resonance. The product achieves high efficiency and low noise power supply systems by
the ZVS and ZCS. The product is recommended for high-efficiency small and
standardized power supplies because of easy circuit designs with few external
components.
Features
z Soft-Switched Multi-Resonant Zero Current Switch (SMZ)
DIP-16
The zero-current switching (ZSC) and zero-voltage switching (ZVS) of half-bridge type resonance achieve the
high efficiency and low noise systems.
z Automatic Dead Time Adjustment Function for Wide Resonant Conditions
z Burst-Oscillation Function
The function enables the stable output control at no load to light load conditions and improves the efficiency.
z Soft-Start Function
z Brown-In / Brown-Out Function
The function enables the oscillation start /stop by externally rated input voltage and makes protections at low
input voltage.
z External Latch Protection (ELP)
The function enables the latch shutdown by external signal.
z Various Protections
Overcurrent Protection (OCP) ---------------------------------Auto-Restart
Three-step protections depending on overcurrent status
Overload Protection (OLP)-------------------------------------Latch Shutdown
Overvoltage Protection (OVP)---------------------------------Latch Shutdown
External Latch Protection (ELP) ------------------------------Latch Shutdown
Thermal Shutdown Protection (TSD)-------------------------Latch Shutdown
Applications
Switching Power Supplies for
Digital Consumer Equipment; LCD-TVs, PDP-TVs, etc.,
OA Equipment; Severs, Multi-Function Printers, etc.,
Industry Machines, Communication Devices, Others
