Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the HV98101 230VAC Off-Line LED Driver Evaluation Board and covers the following topics:

• HV98101 Device Short Overview

• HV98101 Device Key Features

• What Is The HV98101 230VAC Off-Line LED Driver Evaluation Board?

• Board Technical Specifications

• What Does the HV98101 230VAC Off-Line LED Driver Evaluation Board User’s Guide Include?

1.2 HV98101 DEVICE SHORT OVERVIEW

The HV98101 LED driver integrated circuit (IC) is an off-line, high-power factor, buck-boost controller targeted at general LED lighting products, such as LED lamps and LED lighting fixtures with a maximum power rating of about 15W. The HV98101 IC is specifically designed to work from a nominal 230VAC input voltage.

Valley switching buck-boost converters are preferred in off-line applications since they reduce switching losses. A typical solution is to pair a constant on-time control scheme with valley switching to achieve both high-power factor and good efficiency. However, this control scheme results in a higher Total Harmonic Distortion (THD) and the actual value is dependent on the input and output voltages. The HV98101 IC uses a unique control scheme to achieve high-power factor and low THD simultaneously under all line and load conditions, while maximizing efficiency utilizing valley switching. The average output current is also controlled in a closed-loop manner to achieve high-LED current accuracy.

Another unique feature of the ICs is the boot-strap of the IC supply voltage from the output, as well as the unique valley-sensing scheme, which allows the use of a standard off-the-shelf inductor to minimize the overall system cost.

1.2.1 HV98101 Device Key Features

• Good average LED current regulation

• Better than 5% current accuracy

• Output Overvoltage and Output Short-Circuit protection

• Valley switching buck-boost converter with power factor correction

- High power factor (>0.95)

- Low THD (<10%)

• Uses a standard off-the-shelf inductor

- No auxiliary winding required

• Single input voltage range: 230VAC±15%

• Supports 5W-15W output power

• Available in a small, space-saving SOT-23-6L package

Note: Use only the HV98101 device option for this board.

HV98101 230VAC OFF-LINE LED DRIVEREVALUATION BOARD USER’S GUIDE

Chapter 2. Installation and Operation

2.1 GETTING STARTED

The HV98101 230VAC Off-Line LED Driver Evaluation Board is fully assembled and tested. The board requires the use of an external input voltage source (230VAC nominal) and an external LED load.

2.1.1 Additional Tools Required for Operation

1. A DC ammeter capable of measuring currents up to 200 mA is recommended to measure the LED current under different line and load conditions.

2. An oscilloscope and/or a multi-meter to observe the waveforms and measure the electrical parameters (optional).

2.2 SETUP PROCEDURE

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 195VAC to 280VAC. This can be obtained from an auto-transformer supplied from the mains or an electronic AC power supply (for example, Chroma ATE Inc.'s 61500 series).

The power connectors are the following:

• The input connector, W1, placed on the left side of the board and marked AC, as shown in Figure 2-1.

- The AC input should be connected between AC1 and AC2 terminals of connector W1.

• The output connector, W2, called LED and placed on the right side of the board.

- The Anode of the LED string should be connected to the LEDP terminal (positive) and the cathode of the LED string should be connected to the LEDN terminal (negative).

2.3 HOW DOES THE HV98101 230VAC OFF-LINE LED DRIVER EVALUATION BOARD WORK?

The evaluation board is designed to control the current through the LED load while maintaining high-input power factor (PF) and low Total Harmonic Distortion (THD). The topology used in this evaluation board is an off-line, non-isolated, buck-boost converter.

The IC adopts a novel control mechanism to vary both on-time and switching period at the same instant over the line cycle in such a way as to force the average input current to be proportional to input voltage, realizing high-power factor and low THD, which is independent of the load voltage (VO) (unlike a constant on-time control where the THD is dependent on the LED string voltage).

The LED current (IO) is sensed directly using an external sense resistor RCS and compared to an internal fixed reference (CSREF). An internal transconductance amplifier is used to close the loop on the LED current with an external compensation capacitor. The LED current can be programmed using Equation 2-1.

EQUATION 2-1:

The driver incorporates valley switching (quasi-resonant switching), a technique for reducing switching loss at the turn-on event of the buck-boost converter FET. Valley detect is accomplished by sensing the current sunk into the IND pin when the GATE is low. Apart from the valley detect, the current sunk into the IND pin when the GATE is low is used to sense an output overvoltage or open circuit.

2.4 TESTING THE BOARD

To start testing the evaluation board, follow these steps:

1. Connect the input AC source and LED load as shown in Figure 2-1.

2. Power the board at 230VAC.

3. Check that the voltmeter measures a voltage between 88V and 122V on the LED load.

4. Verify the current through the LEDs. It should be within 95 mA and 105 mA (100 mA ± 5%).

5. If a variable AC source is available, set the input voltage to any value between 195VAC and 264VAC. The LED current should still be within ±5% of 100 mA.

6. Power down the AC source.

ILEDCSREF

RCS-------------------=

Note: There are high voltages present on the board when it is powered up. No part of the board must be handled when the board is being powered.

Note: Since there is significant capacitance at the output, it takes time for the out-put capacitor to discharge once the input AC source is powered down. There is a Green LED indicator on the evaluation board that stays lit as long as high voltage is present on the board.
