SSC9502 Datasheet | Sanken

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 remended for high-efficiency small and standardized power supplies because of easy circuit designs with few external ponents. Features DIP-16 z 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. 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, munication Devices, Others Free Datasheet http://../ Typical Application Circuit Typical Electrical Characteristics and Operation Waveforms Power Supply...
