说明
- HV9921DB1, Demo Board is a complete LED power driver to supply a string of LEDs using the HV9921, an integrated 3-pin high input voltage constant-current buck regulator IC. The HV9921 integrates a 500V switching MOSFET and can operate directly from the rectified universal AC line voltage range of 80 to 265VAC. The current in the LED string is internally programmed to 20mA ±15%. The HV9921DB1 is ideally suited for driving strings of LEDs having forward voltage from 20 to 50V at high efficiency (typically 80% at 120VAC)
