Product Summary

The SSC9513 is a Controller IC for Current Resonant Type Switching Power Supply with Half-Bridge Resonance, High Efficiency and Low Noise. The SSC9513 achieves high efficiency and low noise power supply systems by the ZVS and ZCS. The SSC9513 is recommended for high-efficiency small and standardized power supplies because of easy circuit designs with few external components. The applications of the SSC9513 include Digital Consumer Equipment, LCD-TVs, PDP-TVs, OA Equipment, Severs, Multi-Function Printers, Industry Machines, Communication Devices, Others.

Parametrics

SSC9513 absolute maximum ratings: (1) Input: 380VDC; (2) Output: 24V/8.5A (204W); (3) with Power MOSFET RDS (ON): 0.56Ω.

Features

SSC9513 features: (1)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; (2)Automatic Dead Time Adjustment Function for Wide Resonant Conditions; (3)Burst-Oscillation Function; (4)The function enables the stable output control at no load to light load conditions and improves the efficiency; (5)Soft-Start Function; (6)Brown-In / Brown-Out Function; (7)The function enables the oscillation start /stop by externally rated input voltage and makes protections at low input voltage; (8)External Latch Protection (ELP): The function enables the latch shutdown by external signal.
