Hi all. In the continuing saga of my on again, off again project to dim some LED ropelight, I stumbled across the Supertex website. I've had a look around, and it seems the HV9910 might work perfectly to me. It takes a PWM input, drives an external MOSFET, and is cheap ($1.12 in singles from Mouser). So, has anyone here used one? Here's a link to the product page: http://www.supertex.com/feature_hv9910.html Any comments welcome!
