1.2
HV9805 DEVICE SHORT OVERVIEW
The HV9805 driver integrated circuit (IC) is targeted at general light-emitting diode
(LED) lighting products, such as LED lamps and LED lighting fixtures with a maximum
power rating of about 25W at 120VAC, and about 50W at 230VAC.
A two-stage topology provides true constant-current drive for the LED load while
drawing mains power with high power factor. The first stage, a boundary conduction
mode boost converter, transfers power from the AC line to a second stage, with high
power factor and high efficiency.
The second stage, a linear regulator arranged for operation with low overhead voltage,
transfers power from the first stage to the LED load with true constant current and
protects the LED load from overvoltage that may pass from mains to the output of the
first stage.
The IC is particularly geared to drive a high-voltage LED load. An LED load arranged
as a high-voltage load is capable of offering cost advantages in terms of heat
management and optics.
The boost converter employs a cascode switch for high-speed switching and
convenient generation of the VDD supply. The control device of the cascode switch is
integrated into the HV9805 and is rated for a peak current of 0.7A.
The current for powering the VDD supply is derived by way of an internal connection to
the cascode switch.
Applications which require lower load voltage can be accommodated by adapting the
first stage to the SEPIC topology.

Chapter 2. Installation and Operation
2.1
INTRODUCTION
The HV9805 control IC provides true current drive for LED lamps and fixtures by way
of a simple two-stage power supply topology comprised of a boundary mode (BCM)
boost converter and a linear constant-current regulator. The constant-current regulator
removes the influence of bus voltage variation on the LED load operating and current,
and protects the LED load from potentially damaging transients that may originate from
mains overvoltage events. The IC is targeted at designs operating at a single line
voltage, such as 120VAC or 230VAC, and thus, does not support designs for the
universal input voltage range. The efficiency of the constant-current regulator is
maximized by minimizing the DC component of the headroom voltage.
The main sections of the application are presented in the following chapters.
2.1.1
Board Features
The HV9805 230VAC Off-Line LED Driver Evaluation Board has the following features:
•
•
•
•
2.2
Input Voltage: 230VAC ±15%, at 50 Hz Typical
Output Capability: up to 125 mA
Efficiency: over 90%
Pulse-Width Modulation (PWM) Operation: up to 135 kHz
GETTING STARTED
The HV9805 230VAC Off-Line LED Driver Evaluation Board is fully assembled and
tested to evaluate and demonstrate the HV9805 LED driver.
2.2.1
Powering the HV9805 230VAC Off-Line LED Driver Evaluation
Board
The board is connected directly to 230VAC. A variable AC power supply is needed for
testing and evaluation in the laboratory. The power supply requires an output capability
of at least 1A and a voltage range of 100 to 280VAC. This can be obtained from an
autotransformer supplied from the mains or an electronic AC/AC power supply (for
example, Chroma ATE Inc.’s 61500 series).
The power connectors are the following:
• The input connectors, J1 and J2, are placed on the left side of the board and
marked 230VAC, as shown in Figure 2-1.
• The output connectors, J3 and J4, are called LED+ and LED- and are placed on
the right side of the board.

To power the board, follow these steps:
1. Connect the power at terminals J1, 230VAC~ and J2, 230VAC~.
2. Connect a voltmeter and the LED string at J3 (V+ LED) and J4 (V- LED) connectors,
as shown in Figure 2-1. The LED string can be formed with 132 to 150 LED cells (3
LEDs in parallel), 80 mA SMD LED, 280 mW. An example is shown in Figure 2-2.

HOW DOES THE HV9805 230VAC OFF-LINE LED DRIVER EVALUATION
BOARD WORK?
The board was designed to supply, by means of a common-mode filter, a rectifier; a
boost converter followed by a linear regulator, both conducted by the HV9805 driver
directly from the 230VAC mains; and an LED load; with constant current also controlling
the power factor. The topology used in this evaluation board is a Boundary Conduction
Mode (BCM) boost converter followed by a linear current regulator on the LED side in
order to assure true current and high efficiency.
The HV9805 device has the following regulators:
•
•
•
•
The VDD regulator, which is inside the chip (only the filter capacitor is outside)
The LED current regulator
The headroom voltage regulator
The line current waveform regulator
The LED current can be programmed using Equation 2-1.

RHVT/RHVB

Then:
RHVB

Choose:
RHVT

50 kΩ
Therefore:
The DC level of the bus voltage is regulated to be the total sum of the DC level of the
headroom voltage and the operating voltage of the LED load, and will thereby vary
during operation with changes in the forward voltage of the LED load.
EXAMPLE 2-3:
If a 140 LED string is used, a forward voltage drop of 3V on each LED is assumed.
Then, the Bus Voltage level will be:
VDC = 140 × 3 + VHDC = 420 + 7.5 = 427.5VDC
Note:
In order to have a good Valley detection, choose an LED string voltage
20-30V greater than the peak input voltage (which is usually 264VAC). In
this condition, the minimum LED load voltage is
VLED MIN = 20 + 1.41 × 264 = 392VDC
The power dissipation of the LED current regulator must be low, so the DC level of the
headroom voltage (VHDC) will be minimized, the dissipation being calculated using
Equation 2-3.

BOARD TESTING, TEST POINTS WAVEFORMS AND OVERALL MEASURED
PARAMETERS
2.4.1
Board Testing
To start testing the evaluation board, follow these steps:
1. Power the board at 230VAC.
2. Check that the voltmeter indicates the LED load voltage (do not exceed 440VDC).
3. With a power supply of 230VAC, verify if the current regulated through the LED
strings is about 90 mA (by means of an ampere-meter connected in series with
the LEDs).
The following steps are possible if a variable AC power supply or an autotransformer
is available:
4. Set the power supply to 190VAC and verify if the output current on the LED side
stays regulated (IOUT ~90 mA).
5. Set the power supply to 270VAC and verify if the output current on the LED side
stays regulated (IOUT ~90 mA). Also, check that the voltage stays regulated on
V2 near the value 415V.
