Check out this link for just TI's options. I D/L'd it last year when I was working on a design with my brother. Most use boost or buck switchers with FETs and small current sense resistors and include dimming inputs. My main problem is that it's harder and harder to find PDIPs or CDIPS and I detest surface mount. I get the EDN emails at work and all Im'seeing is LED lighting. There is a lady there who tears down new incandescent replacements that comes along. I'll post a link later.
