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-to-

peak 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).
