XR46110 Datasheet | MaxLinear

Description The XR46110 is an LED current controller with line regulation pensation for operating over a wide alternative current (AC) voltage source range. It can drive an external N-channel power MOSFET to regulate the current flowing through a high voltage (HV) LED string. The application of the XR46110 is configured in series with an LED string, working as a constant current sink with linear type overvoltage protection (OVP), linear type over temperature protection (OTP), and line regulation pensation. It is suitable for applications with a rectified AC voltage source. The PCB design can be very pact to meet various shape requirements. It is especially suitable for replacing incandescent light bulb and linear type fluorescent lamps.
