MaxLinear XR46110
The XR46110 is an LED current controller with line regulation compensation 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 compensation.| Part No. | XR46110 |
