XR46110 LED Current Controller with Line Regulation Compensation Description FEATURES The XR46110 is an LED current controller with line regulation Device compensation for operating over a wide alternative current (AC) 6V to 78V chip supply voltage range Excellent system power regulation in voltage source range. It can drive an external N-channel power 10% AC mains fluctuation MOSFET to regulate the current flowing through a high voltage (HV) Over temperature protection LED string. Overvoltage protection The application of the XR46110 is configured in series with an LED Single board LED lighting solution string, working as a constant current sink with linear type overvoltage available 2mm x 2mm TDFN-6 package protection (OVP), linear type over temperature protection (OTP), System and line regulation compensation. It is suitable for applications with a All solid state components rectified AC voltage source. No electrolytic capacitor required The PCB design can be very compact to meet various shape Scalable architecture allows requirements. It is especially suitable for replacing incandescent light optimization of performance vs. cost Driver-on-board and chip-on-board bulb and linear type fluorescent lamps. design solution available which minimize process flow and assembly cost Typical Application High PF and low THD performance Flexible PCB layout options + APPLICATIONS LED Lighting Applications V AC Downlight LEDS1 High bay BD Specialty Architectural LEDS2 U1 XR46084 R1 R R A1 IN1 130 LEDS3 U2 R R A2 IN2 120 XR46084 110 R2 100 RG Q1 90 VIN GATE XR46000 VL NC 80 GND CS C LR R B 70 U3 R3 108 114 120 126 132 XR46110 V (V) AC Figure 1.
