XR46050
XR46050 is Two-Step LED Current Controller manufactured by MaxLinear.
Description
The XR46050 is a two-step LED current controller for bulb application powered by an alternative current (AC) voltage source directly. It can drive an external N-channel power MOSFET to regulate the current flowing through a High Voltage (HV) LED string.
The XR46050 works as a constant current regulator to control two-step current levels for AC step driver with simplest structure. It also provides linear type Over Temperature Protection (OTP).
The PCB design can be very pact to meet various shape requirements. It is especially suitable for replacing A-series LED light bulbs and candelabra LED bulbs.
