  • Page 11: Chapter 1. Product Overview

    The single-ended primary-inductor converter (SEPIC) configuration extends the appli- cation range of the HV9805 driver Integrated Circuit (IC) to lower LED load voltages than otherwise possible with the boost configuration. Many features of the boost con- figuration are retained, such as a true direct current drive of the LED load, high input power factor, high efficiency and simple magnetics.

  • Page 12: Device Summary

    HV9805 DEVICE SUMMARY The evaluation board features the HV9805 LED driver IC. The HV9805 device is described in the HV9805 Data Sheet – “Off-Line LED Driver with True DC Output Cur- rent” (DS20005374). The standard HV9805 application circuit supplies a true DC current to the LED load by using a converter for AC to DC power conversion, and a linear post regulator for con- stant current regulation of the LED load current.

  • Page 13: Chapter 2. Installation And Operation

    • A power analyzer for measuring the AC power and the AC power factor • An oscilloscope for characterizing waveforms • A variable transformer for adjusting the AC line voltage • An isolation transformer (if an oscilloscope is attached to board circuitry)  2015 Microchip Technology Inc. DS50002362A-page 13 Arrow.com. Arrow.com.

  • Page 14: Setup Procedure

    The AC voltage can either be applied in full or be brought up gradually with a variable transformer. The external circuit for the HV9805’s BVS pin has been adapted to the SEPIC topology, offering protection against line undervoltage and against output overvoltage or an open load condition.
