XR46010 Active Load Current Regulator for Phase-Cut Dimmable AC Direct Drive LED Lamp Description The XR46010 is an active load current regulator for phase-cut dimmable AC direct drive LED lamp system. The active load circuit can provide the holding current for TRIAC and also the charging current path of R/C circuit in a dimmer. It can help to stabilize TRIAC operation and increase the dimming range of the lamp system. The application of the XR46010 is configured in parallel with an LED string. It conducts the current when the LED string is in off state, and stops conducting the current when the LED string is in on state. The active load circuit can be placed in the same board with the LED string or a separate board in front of the LED board.
