LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS
- DESCRIPTION
The UTC UC3800 is a high performance current mode PWM controller ideally suited for low standby power. High voltage startup is implemented in UTC UC3800, which Features with short startup time and no standby current. At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency for higher conversion efficiency at light load condition.
The internal slope pensation improves system stability at high PWM duty cycle output. Leading-edge blanking on current sense input removes the signal...
