MT7641F is a controller for removing LED 100/120Hz current ripple. Through the internal low-pass filter removes low frequency current ripple and LED flicker.

MT7641F integrates startup circuit to shorten the time of reaching a stable state. The output current is less than 30mA. Connect multiple MT7641F in parallel to realize a higher output current.

MT7641F is available in SOT23-3 package, especially suitable for small size lamps.



  • Low-pass filter to remove current ripple
  • Quick start
  • Multiple chips connected in parallel to increase output current
  • Available in SOT23-3 packages
