Hi Guys,

I want to drive one XM-L in two different diving lamp with only one on/off-switch and need two different drivers:

First Driver: Input 9...15V (10*NiMh) -> XM-L@ about 4A and: The Driver must be at 100%-Mode after powering up because only one switch available. Max. Diameter 27mm, smaller is better :)

Second Driver: Input 9...15V (10*NiMh) -> XM-L@ about 2A and: The Driver must be at 100%-Mode after powering up because only one switch available. Continuous duty without or with small heatsink must be possible. PCB must not be round. An efficient buck converter (Constant Voltage) with these Specs would be okay, too... I would then drive it with a little series resistance.

Thanks in Advance
