Chapter 1. Product Overview
1.1 INTRODUCTION
The HV9805 230VAC SEPIC Evaluation Board is suited for driving a 125V/100 mA LED
load from a 230VAC source.
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.
The SEPIC configuration can be used to advantage with any of the common AC voltage
levels, such as 100VAC, 120VAC, 230VAC, 277VAC and 24VAC.
Note that the boost topology can process more power than the SEPIC topology for a
given current rating of the converter switch. Whereas the switch of the boost topology
carries the line current only during on-time of the switch, the switch of the SEPIC
topology carries both the line current (inductor current L51) and the load current
(inductor current L50) during on-time of the switch. Accordingly, the power handling
capability of the SEPIC converter is lower than the boost converter for a given current
rating of the switch. It is also worth noting that the SEPIC power rating drops with output
voltage, since a lower output voltage translates into a larger load current and thereby
a larger switch current.

1.3 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. By nature of the boost converter, the
LED load voltage should be higher than the peak AC line voltage.
A lower LED load voltage can be accommodated by the use of a SEPIC converter. The
SEPIC provides a solution where the LED load voltage is either higher or lower than
the peak AC line voltage; as the SEPIC converter is capable of bucking and boosting
the input voltage.
1.4 NOTES ON THE EVALUATION BOARD DESIGN
1.4.1 Surge Protection and Voltage Withstand Capability
The evaluation board demonstrates the basic functionality of the HV9805 in a SEPIC
configuration. No special effort was made to include measures for transient overvoltage
protection. Such protection typically involves the addition of at least one stage of
metal-oxide varistor (MOV) protection and the coordination of the voltage withstand
capability of components exposed to line voltage transients.
1.4.2 LED Current Regulator Oscillation
The first-released evaluation board exhibits high-frequency oscillation of the drain volt-
age of pass transistor M2. This oscillation does not affect the functionality of the board
significantly.
The drain voltage oscillation can be suppressed by including 100 kΩ in series with the
gate lead of pass transistor M2.
The traces relating to the headroom voltage (test points REG and HVS), as shown in
Appendix D, were captured with the suppression resistor in place.
1.4.3 Harmonic Distortion
Harmonic distortion can be lowered by increasing the capacitance of the compensation
capacitor C4.
1.5 WHAT DOES THE HV9805 230VAC SEPIC EVALUATION BOARD INCLUDE?
The HV9805 230VAC SEPIC Evaluation Board includes:

Chapter 2. Installation and Operation
2.1 SAFETY CAUTION
2.2 GETTING STARTED
The HV9805 230VAC SEPIC Evaluation Board is fully assembled and tested. The
board requires the use of an external AC source (230VAC) and an external LED load
(125VDC, 100 mADC).
The board features metal loop-style test points for making connections to the AC line
and the LED load and test vias for probing certain circuit nodes.
2.2.1 Additional Tools Required or Desirable for Evaluation
A list of additional tools that are required or may be used during evaluation include:
• DC and AC voltage and current meters
• 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)
WARNING
Workin g with this boa rd can cause serious bodily harm or dea th. Connecting the board
to a source of line voltage will result in the presence of hazardous voltage throughout
the syste m incl uding the L ED load a nd any at t ached instru ment atio n. The board should
only be handled by persons well aware of the dangers involved with working on live
electri cal equi pme nt.
Extreme care should be taken to protect against electric shock. Disconnect the board
before attempting to make any changes to the system configuration. Always work with
another person nearby who can offer assistance in case of an emergency.
Wear safety glasses for eye protection.
NOTICE
The electrolytic capacitor C50 carries a hazardous voltage for an extended time after
shutdown of the LED driver board. Capacitor C50 will slowly discharge by way of
resistors R18 and R19, as well as test point W3, the LED load, test point W4 and
resistors R15 and R11, or at a faster rate if a resi stor is purposely added across th e
terminals of capacitor C50. Check the capacitor voltage before handling the board.
Observe pola r ity for all steps to prevent board dama ge.

DS50002362A-page 14 2015 Microchip Technology Inc.
2.3 SETUP PR OCEDURE
To operate the HV9805 230VAC SEPIC Evaluation Board, the following steps must be
completed:
1. Attach the LED load to the output test points W3 and W4, labeled as POS and
NEG on the board. Observe the polarity of connections. Connect the anode of
the LED load to test point W3 (POS) and the cathode to test point W4 (NEG).
2. Connect the AC source to the input test points W1 and W2. Both terminals are
also marked as ‘AC’.
2.3.1 AC Input Considerations
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.
The undervoltage lockout circuit (R12, R13, R14, C6, D1) disables the driver when the
line voltage is less than approximately 200VAC when the bus voltage is zero. The
threshold changes to a lower value when a non-zero bus voltage is present. A non-zero
bus voltage can be the result of driver operation prior to a shutdown event, or can be
caused by a gradual build-up when the line voltage is gradually increased by a variable
transformer. A more sophisticated circuit is required if the undervoltage threshold
dependency on bus voltage is undesirable.
The overvoltage protection circuit disables the driver when the output voltage rises
above 150VDC. The output overvoltage protection is non-latching, meaning that the
driver will cyclically turn on and off when an LED load overvoltage condition or an out-
put open circuit condition is present.
2.3.2 LED Load Considerations
The driver is designed for a load voltage of 125VDC and a load current of 100 mADC.
The load current is fixed and set by the resistors R17 and R20.
The board can be operated with substantially lower LED voltage. Operation at lower
LED voltage results in loss of efficiency, lower power factor and higher harmonic distor-
tion, as shown in Tab l e 2- 1.
2.4 EVALUATING THE APPLICATION
Typical voltage and waveforms are provided in Appendix D. “Test Points and

D.2 WAVEFORM EXAMPLES
The voltage waveforms in the following oscillograms are marked with the name of the
corresponding test points. Current waveforms were taken with a DC current probe.
Line current was measured by attaching the probe to an AC input lead and the LED
current was measured by attaching the probe to an output lead. The inductor currents
L50 and L51 were measured by inserting temporary leads in series with the inductors
and attaching the probe to the temporary leads.
