Quasi-Resonant Off-Line Switching Control ICs

SSC1S310A Series

Data Sheet

Description

V_OUT

VAC

SSC1S310A series is the controller ICs of a quasi-

resonant 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 mode is

automatically changes the quasi-resonant mode to the

bottom-skip mode to improve efficiency. The IC is

provided in the SOIC8 package. The power supply that

is a low component counts and a high performance-to-

cost can be achieved by the rich set of protection

features.
