SSC1S311A Description
SSC1S310A series is the controller ICs of a quasiresonant mode for a switching power supplies. The IC incorporates a startup circuit and a standby function to reduce a power consumption and standby power. In normal operation, the quasi-resonant mode operation achieves high efficiency and low noise.
SSC1S311A Key Features
- Multi-Mode Control (High efficiency operation in all range of loads)
- Automatic Standby Function (Standby power is inproved by burst oscillation mode)
- Input Power at No Load: <30mW at 100 VAC <50mW at 230 VAC
- 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
