説明
- HV9967BDB1, Demo Board is a high-brightness LED driver designed to drive 4 LEDs in series at currents up to 350mA from a 20 - 60 VDC input. The demo board uses the HV9967B in a buck configuration in a constant off-time mode. The HV9967BDB1 LED driver features tight regulation of the LED current within a few milliamps over the entire range of the input voltage (i.e. 20 - 60VDC). The LED current accuracy is almost insensitive to the passive component tolerances, such as the inductance or the timing resistor. PWM dimming can be achieved by applying a pulse-width modulated square wave signal between the PWMD and GND pins
