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.

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).
