Hi,
We are developing 2 LED driver models for a 2 and 4 lamp T8 lighting product.
Each lamp contains 90 LEDs. We have the option of having 3 30 string LEDs in parallel or 6 strings of 15 LEDs in parallel.
The 3 string lamp will require a Vf of 90 at 180ma. The 6 string lamp will require a Vf of 45V at 360ma. We are doing this so we can have some flexibility in choosing the driver.
So model one will drive 2 lamps with 90V at 360ma. or 45V at 720ma. Model two will drive 4 lamps at 90V at 720ma. or 45V at 1.44A
Any help would be greatly appreciated.
Thanks
