The XR46203 is a two-step LED current controller with line regulation compensation for operating over a wide alternating 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 XR46203 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. The XR46203 is especially suitable for replacing incandescent light bulbs and linear-type fluorescent lamps.
