XR46073
Two-Step LED Current Controller with Line Regulation Compensation
Description
The XR46073 is a two-step 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 XR46073 works as a constant current sink with linear type Overvoltage Protection (OVP), linear type Over Temperature Protection (OTP) and line regulation compensation. It is suitable for applications with a rectified AC voltage source.
The PCB design can be very compact to meet various shape requirements. It is especially suitable for replacing incandescent light bulbs.
