KTD2692 is the ideal power solution for high-power flash LEDs.
|
||
|
|
It uses ExpressWire single-wire programming for maximum flexibility.
|
||
|
|
|
||
|
|
The ExpressWire interface through CTRL pin can control LED on/off and
|
||
|
|
enable/disable the IC, Movie(max 1/3 of Flash current) / Flash mode current,
|
||
|
|
Flash timeout, LVP(low voltage protection).
|
||
|
|
|
||
|
|
Also, When the AUX pin is pulled high while CTRL pin is high,
|
||
|
|
LED current will be ramped up to the flash-mode current level.
