LED Driver A6261: Protected LED Array Driver
LED Driver A6261: Protected LED Array Driver
DESCRIPTION:
The A6261 is a linear, programmable current regulator providing up to 100 mA from each of four outputs (LP and LY) to drive arrays of high brightness LEDs. The regulated LED current from each output, accurate to 5%, is set by a single reference resistor. Current matching in each string is better than 10% without the use of ballast resistors. Driving LEDs with constant current ensures safe operation with maximum possible light output. The A6261 in the LJ package offers two pins with 200 mA each channel (A6261LJ-1) and with 100 mA and 200 mA maximum output current (A6261LJ).
