The LM3445-120VSMEV is a LM3445, 110V off line TRIAC dimmer LED board converts 90VAC to 135VAC input and drives seven or eight series connected LEDs at 350mA average current. The LM3445 switching frequency is set at a nominal 225kHz. This is a four layer board using the bottom and top layer for component placement. The evaluation board can be modified to adjust the LED forward current, the number of series connected LEDs and switching frequency.
● Triac dim decoder circuit for LED dimming
