LOW COST POWER-SAVING MODE PWM CONTROLLER FOR FLYBACK CONVERTERS

The?UC3863 is a high performance current mode PWM controller ideally suited for low standby power. The PWM switching frequency is programmable externally at normal operation. Low VDD startup current make the power reliable on startup design and a large value resistor could be?used in the startup cir ? UTC proprietary frequency hopping technology for Improved EMI performance.?\n? Power-saving mode for high light-load and standby efficiency \n? Dynamic peak current limiting for constant output power \n? Built-in synchronized slope compensation \n? OTP,OLP,OVP and VDD clamp for higher security \n?;

具有 8/7V UVLO、交替輸出和固定關(guān)斷時間、溫度范圍為 0°C 至 70°C 的諧振模式 PWM

The UC1861-1868 family of ICs is optimized for the control of Zero Current Switched and Zero Voltage Switched quasi-resonant converters. Differences between members of this device family result from the various combinations of UVLO thresholds and output options. Additionally, the one-shot pulse stee ?
