- AT9919DB1, Demo Board for AT9919 Single, High Current LED Driver. The AT9919BDB1 Demo Board is a high current LED driver designed to drive one LED at 1.0A from a 9.0 - 16VDC input. The Demo Board uses an AT9919 hysteretic buck LED driver IC. The AT9919DB1 includes two PWM dimming modes. The analog control of the PWM dimming mode allows the user to dim the LED using a 0 - 2.0V analog signal applied between the ADIM and GND pins (0V gives 0% and 2.0V gives 100%). In this mode, the PWM dimming frequency is set to 1kHz on the board. The digital control of PWM dimming mode allows the user to dim the LEDs using an external, TTL-compatible square wave source applied between DIM and GND
