SSC9510 Series
Controller IC for Current Resonant Type Switching Power Supply
with Half-Bridge Resonance, High Efficiency and Low Noise
■
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
DIP-16
SOP-18
ꢀ
ꢀ
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.
