Description
SSC1S311A is the controller IC of a quasi-resonant mode for a switching power supplies. The IC incorporates a startup circuit and a standby function to reduce power consumption and standby power. In normal operation, the quasi-resonant mode achieves high efficiency and low noise. In addition, in medium to low load conditions, the operation mode automatically changes to the bottom-skip mode to improve efficiency. The IC is provided in the SOIC8 package. The power supply that has a low component count and a high performance-to-cost ratio can be achieved by the rich set of protection features.
Specifications and features
● Multi-Mode Control (High efficiency operation in all range of loads) ● Automatic Standby Function (Standby power is improved by burst oscillation mode) ● Input Power at No Load: - <30mW at 100VAC - <50mW at 230VAC ● Bottom-Skip Function (Switching loss in medium to low loads is reduced) ● Step-on Burst Oscillation Function (Transformer audible noises are reduced) ● Bias Assist Function ● Soft-Start Function ● Adjustable Startup Voltage ● Maximum On-time Limitation Function ● VCC Operational Range Expanded ● Leading Edge Blanking (LEB) Function (External Filter Components are reduced) ● Protection Functions: - Overcurrent Protection (OCP): Pulse-by-pulse - Overvoltage Protection (OVP): Auto-restart - Overload Protection (OLP): Auto-restart - Thermal Shutdown (TSD): Auto-restart
Application Scenarios
● Digital Appliance ● Office Automation (OA) Equipment ● White Goods ● Industrial Apparatus ● Communication Facilities
