UNISONIC TECHNOLOGIES CO., LTD  
UC3846  
LINEAR INTEGRATED CIRCUIT  
LOW COST POWER-SAVING  
MODE PWM CONTROLLER  
FOR FLYBACK CONVERTERS  
„
DESCRIPTION  
The UTC UC3846 is a high performance current mode PWM  
controller ideally suited for low standby power and cost effective  
off-line flyback converter.  
DIP-8  
Low VDD startup current make the power reliable in startup  
design and a large value resistor could be used in the startup  
circuit to minimize the standby power. At no load condition, the  
IC operates in burst mode for lower standby power and in  
decreasing frequency for higher conversion efficiency at light  
load condition. The PWM switching frequency is programmable  
externally at normal operation.  
The UTC UC3846 contains protection coverage with  
automatic self-recovery including OCP (cycle-by-cycle current  
limiting), OTP (over temperature protection), UVLO (VDD over  
voltage clamp and under voltage lockout).To protect the power  
MOSFET, Gate-drive output is fixed up to 15V max.  
The internal slope compensation improves system stability at  
high PWM duty cycle output. Leading-edge blanking on current  
sense (CS) input removes the signal glitch that offers minimal  
reqnirement of external component and lower system cost.  
Excellent EMI performance is achieved by UTC proprietary  
frequency hopping technique together with soft driver control.  
Audio noise is eliminated because switch frequency is more  
than 20kHz during operation.  
„ FEATURES  
* UTC proprietary frequency hopping technology  
for Improved EMI  
* performance.  
* Power-saving mode for high light-load efficiency  
* Burst mode for minimum standby power  
* Dynamic peak current limiting for constant output  
power  
* Built-in synchronized slope compensation  
* OTP,OVP and VDD clamp for higher security  
* Programmable PWM Frequency  
* Gate output voltage clamped at 15V  
* Low start-up current  
The UTC UC3846 can be used in the applications, such as  
battery charger, power adaptor, set-top box power supplies, ink  
jet printers open-frame SMPS  
* Cycle-by-cycle Current Limiting  
* Under voltage lockout (UVLO)  
* Few external components required
