SSC1S310A - Sanken

SSC1S310A Quasi-Resonant Off-Line Switching Controller

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. In addition, in medium to low load conditions, the operation.

Features
