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.
 Fixed 65kHz PWM switching frequency.
 Leading-edge blanking on current sense.
 Internal synchronized slope compensation.
 Low standby power consumption (<75mW@AC
230V)
 Soft-start to reduce MOSFET Vds stress
during power on
 Comprehensive protection function
1、Under voltage locked with hysteresis
(UVLO) on VCC.
2、Over voltage protection (OVP) on VCC.
3、Cycle-by-Cycle current limitation.
4、Over load protection (OLP)
5、Over temperature protection (OTP)
6、Current limitation compensation to
obtain the same output current in universal
ac line input
 Low start-up current (<10uA@VCC=12V)
Applications
 Cell Phone Charger
