■ 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
