HV9910BDB2, Universal, Off-Line, High-Brightness, 350mA LED Driver Demo Board

HV9910BDB2, Demo Board is a High-Brightness LED power driver to supply a string of LEDs using the HV9910B IC from a universal AC input. The HV9910BDB2 can supply a maximum output current of 350mA to drive 10 - 40V LED strings from a wide input voltage - 90 to 265VAC, 50/60Hz. The power conversion stage of the HV9910BDB2 consists of a diode bridge rectifier, followed by a current-controlled buck converter operating at a switching frequency of 50kHz. The nominal output current of the demo board can be adjusted to any value between 30 and 350mA using the on-board trimming potentiometer
