... DC input. The demoboard uses the Supertex’s 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. 60VDC). The LED current accuracy is almost insensitive to the passive component tolerances, such as the output filter inductance or the timing resistor ...
