Description
- HV9919BDB1, Demo Board is a high current LED driver designed to drive one LED at 1A from 9 - 16V DC input. The demo board uses HV9919 hysteretic buck LED driver IC. The HV9919BDB1 includes two PWM dimming modes. The analog control of the PWM dimming mode allows the user to dim the LED using a 0 - 2V analog signal applied between the ADIM and GND pins (0V gives 0% and 2V 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
