The XR46010 is an active load current regulator for phase-cut dimmable AC direct drive LED lamp systems. The active load circuit can provide the holding current for the TRIAC and also the charging current path of the R/C circuit in a dimmer. It can help to stabilize the TRIAC operation and increase the dimming range of the lamp system.
The XR46010 is configured to work in parallel with an LED string. It conducts the current when the LED string is in the “off” state, and stops conducting the current when the LED string is in the “on” state.
The active load circuit can be placed on the same board with the LED string or a separate board in front of the LED board. The design is very flexible to meet various shape requirements. It is especially suitable for LED light bulbs and tubes.
