UC3875A | LOW COST POWER-SAVING ?MODE PWM CONTROLLER FOR FLYBACK CONVERTERS The UTC UC3875A 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 start UTC proprietary frequency hopping technology for Improved EMI performance.?Power-saving mode for high light-load and standby efficiencyDynamic peak current limiting for constant output powerBuilt-in synchronized slope FBensationOTP,OLP,OVP and VDD clamp for higher securityProgrammable PWM FrequencyG; | UTC 友順 | UTC |
