SSC1S312A
Sku:
SSC1S312A
Features
- High efficiency in all range of loads
- Burst oscillation mode lowers standby power
- Bottom-skip function improves efficiency at low loads
- Leading edge blanking reduces external components
- Rich protection functions OVP, OCP, OLP, thermal shutdown
The SSC1S312A is the controller IC for a quasi-resonant mode switching power supply.
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.
In addition, in medium to low load conditions, the operation mode is automatically changed from the quasi-resonant mode to the bottom-skip mode to improve efficiency.
The resulting power supply uses less components and achieves a high performance-to-cost with a rich set of protection features.
The IC is provided in the SOIC8 package.
