This chapter provides an overview of the HV9805 230VAC Off-Line LED Driver
Evaluation Board and covers the following topics:

• HV9805 Device Short Overview

• What is the HV9805 230VAC Off-Line LED Driver Evaluation Board?

• What does the HV9805 230VAC Off-Line LED Driver Evaluation Board Include?

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 120V

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 V
integrated into the HV9805 and is rated for a peak current of 0.7A.

The current for powering the V
the cascode switch.

Applications which require lower load voltage can be accommodated by adapting the
first stage to the SEPIC topology.

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 120V
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:

• Input Voltage: 230V

• Output Capability: up to 125 mA

• Efficiency: over 90%

2.2 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 280V
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 230V

• 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, 230V

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.

2.3 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 230V
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 V

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
