18W Non-isolated Led Driver with LYT5218
We design the 18W LED Driver with LYT5218.
I have two queries,
1. How can i select the SHUNT Resistor
2. The Driver is Working, But i have an issue when i put it into aluminium enclosure. LED Driver wattage will increase 2Watts with Aluminium enclosure. Why this is happening and How can i rectify it.
Please Help Me...
