■ 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
■ Applications
