7 title: KTD2692 Flash LED Driver from Kinetic Technologies
10   - Markuss Broks <markuss.broks@gmail.com>
13   KTD2692 is the ideal power solution for high-power flash LEDs.
14   It uses ExpressWire single-wire programming for maximum flexibility.
16   The ExpressWire interface through CTRL pin can control LED on/off and
17   enable/disable the IC, Movie(max 1/3 of Flash current) / Flash mode current,
21   LED current will be ramped up to the flash-mode current level.
