4W LED Driver Demoboard with Accurate Average-Mode Constant Current Control

Part Number: HV9967BDB1

Summary:

The HV9967BDB1 demoboard is a high-brightness LED driver designed to drive 4 LEDs in series at currents up to 350mA from a 20 - 60V DC input. The demoboard 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).
