Beschreibung
- Evaluation Board included in this shipment is capable of converting a 176VAC to 305VAC input that has been phase dimmed to drive multiple LED's at up to 500 mA average current. The Evaluation board utilizing the LM3445 will automatically adjust the LED current and light output in relation to the TRIAC firing angle. The target solution for this design was 230VAC input driving 8 series connected white LEDs. In this configuration the LM3445 will run at a nominal switching frequency of 80 kHz and supply a maximum of 350 mA
