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