MT7641B

Description

MT7641B is a controller for removing LED 100/120Hz current ripple. Through the internal low-pass filter removes low frequency current ripple and LED flicker.

MT7641B integrates startup circuit to shorten the time of reaching a stable state. Output current is up to 70mA (SOT89-3). Connect multiple MT7641B in parallel to realize a higher output current.

MT7641B is available in SOT23-3 package, especially suitable for small size lamps.
