A6211-Slide7

The A6211 demo board allows users to drive high brightness LEDs directly from a DC source of 6V - 48V. The enable pin’s wide voltage range increases system versatility by not requiring an additional voltage rail in order to activate the part. This is beneficial in applications such as PoE lighting and camera surveillance where a second voltage line is typically not needed. This pin also accepts an optional PWM signal for dimming, thus enabling intelligent control from microprocessors, DSPs, and various other digital controllers. For constant light at the jumper current setting, the enable pin is simply tied to a constant voltage level within the threshold range of 1.8V to (Vin + 0.3) volts.
