I've been looking at the stickies and it looks like a lot of drivers offered my LPF members are out of production. I'm building a pen with an Osram PLT5510 diode which operates between 60-100mA at 5.4-7V, but most drivers I've found offer anything from 100mA and up, which is not ideal because I want to drive it under the maximum current. I'm also hopefully looking for a boost driver so I don't have to drive it with over 5v because I don't want the pen to use large batteries like two 18650s. Are there any drivers in production right now?
