Dear Sir,

              I want to implement DER 256 LED Driver for T8 Lamp.I Want to modify the design to meet the following requirement:

sPECIFICATION: INPUT:90-265VAC,OUTPUT:45 V,400mA

KEY GOALS:

1.Meet 2 KV differential Surge

2.Meet 4KV Commonmode surge

3.IEC 6100-4-5  2.5 KV Ring Wave 

4.Must be fit inside T8 Tube Enclosure
