XR46050 Two-Step LED Current Controller

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 regula.
