■ General Descriptions The SSC9510 series products are controller ICs, 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
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 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
