Supertex inc. HV9910BDB7 HV9910B PFC 40W LED Driver Demoboard General Description The Supertex HV9910BDB7 demonstrates the use of an HV9910B control IC in an off-line, High Brightness LED driver application. The board incorporates power factor correction (PFC) and satisfies the limits for harmonic currents according to the EN61000-3-2 Class C standard having total harmonic distortion (THD) less than 20%. The board features a low component count and long life operation due to the absence of electrolytic capacitors. The board is designed to supply a string of LEDs with a current of 350mA and a voltage in the 65 to 105V range from a 220/230VAC line. The conversion stage draws line current throughout the AC line cycle, partly using a charge pumping and partly using a boost conversion technique to charge the bulk energy storage capacitors. The LED current is provided with a continuous mode buck stage giving a DC current with about 30% peak-topeak ripple. A patent for this conversion technique is pending. Please inquire with the Supertex applications department for design guidance, should change of input line voltage, output voltage, or output current be desired. An effort was made to satisfy the requirements of CISPR 15 (EN55015), limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment. Specifications Parameter Value Input voltage 190~265VAC, 50Hz Power factor 0.95 <20%; EN 61000-3-2 Class C Total harmonic distortion EMI limits CISPR 15 Output voltage 65~105V Output current 350mA±10% Output power 40W Efficiency 90% Load regulation <3% AC Line regulation <1.5% Output ripple <30% peak-peak Life time Non-Electrolytic Output short circuit protection No Output open circuit protection Yes Dimensions 3.0” x 2.3” x 1.1” (76mm x 58mm x 28mm) The connection diagram details the hookup of the board to the AC line. Note that the load is NOT galvanically isolated, and that measurements to the board require measurement techniques in common use with non-isolated off-line power supplies (isolation transformers, differential probes, etc).
