S1109SC
Description
S1109SC combines a dedicated current mode PWM
mode controller with a 1Ω/650V MOSFEET.
S1109SC has high efficiency, low standby power
consumption, low EMC and low cost. It is applied to
the off-line flyback converter in the range of 20W
output power.
S1109SCoffers comprehensive protection functions,
including Cycle-by-Cycle current limitation (OCP),
over temperature protection (OTP), Over voltage
clamp (OVP)and under voltage lockout (UVLO) on
VCC.
S1109SC is offered in SOP8 package.
Features
 Digit frequency shuffling technology to improve
EMI performance.
