We are using LED lamp with the following technical details and I am looking forward to have suitable LED driver design with appropriate IC for future development.
Input voltage: 90 - 280 Vac/Vdc or only 90 - 280 Vac
Watt : 1 watt to 2 watt
LED lamp will be used in constant voltage and current along with the heater circuit.
circuit should have inbuilt surge/spike voltage/high voltage control system.
circuit should be ripple free i.e. filter circuit.
