13 KTD2692 is the ideal power solution for high
14 It uses ExpressWire single-wire programming

16 The ExpressWire interface through CTRL pin c
17 enable/disable the IC, Movie(max 1/3 of Flas
18 Flash timeout, LVP(low voltage protection).

20 Also, When the AUX pin is pulled high while
21 LED current will be ramped up to the flash-m
