Off-line Controller for LED Lighting XC9401 Series

The XC9401 series are off-line controllers for LED lighting. Operation within the range 85VAC - 270VAC and by DC input is possible. Fixed off time control is used as the basic method, and with detecting the current that flows to the external power MOSFET, the current flowing to the LED is monitored and stable power for LED lighting is supplied. The XC9401 series provides simple operation, that can be applied to non-isolated and isolated circuit solutions. XC9401 A-type is designed to achieve a high power factor. The XC9401 B-type is able to maintain a constant LED current. The SOT-26 package enables reduction of the board mounting area.
