Product Overview 1.1 INTRODUCTION This chapter provides an overview of the HV9805 120VAC Off-Line LED Driver Evaluation Board and covers the following topics: * HV9805 Device Short Overview * What Does the HV9805 120VAC Off-Line LED Driver Evaluation Board Do? * What is Included in the HV9805 120VAC Off-Line LED Driver Evaluation Board Kit? 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 an approximate maximum power rating of 25W at 120VAC and 50W at 230VAC. A two-stage topology provides true constant current drive for the LED load while drawing mains power with a high power factor. The first stage, a Boundary Conduction mode boost converter, transfers power from the AC line to a second stage, with a 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 that require lower load voltage can be accommodated by adapting the first stage to the SEPIC topology. 2015 Microchip Technology Inc.

HV9805 120VAC OFF-LINE LED DRIVER EVALUATION BOARD USER'S GUIDE 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. 2.1.1 Board Features The HV9805 120VAC Off-Line LED Driver Evaluation Board has the following features: * * * * * Input Voltage: 120VAC 15%, at 60 Hz Typical Output Current: 90 mA 5% Efficiency: over 90% Switching Frequency: up to 135 kHz Output LED String Voltage: 240V (nom) 2015 Microchip Technology Inc. DS40001785A-page 15 HV9805 120VAC Off-Line LED Driver Evaluation Board User's Guide 2.2 GETTING STARTED The HV9805 120VAC Off-Line LED Driver Evaluation Board is fully assembled and tested to evaluate and demonstrate the HV9805 LED driver. 2.2.1 Powering the Evaluation Board The board is connected directly to 120VAC. 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 from 0 to 150VAC. This can be obtained from an autotransformer supplied from the mains or an electronic AC/AC power supply (for example, the Chroma ATE Inc. 61500 series). The power connectors are listed here: * The input connectors, J1 and J2, are placed on the left side of the board and marked 120VAC ~, as shown in Figure 2-1. * The output connectors, J3 and J4, are called LED+ and LED- and are located on the right side of the board. V1Meter + Electronic LED Load/ Configurable LED Load Board - ~ Adjustable 120VAC Power Supply ~ FIGURE 2-1: V2Meter Connection Diagram. To power the board, follow these steps: 1. Connect the power at J1, 120VAC~ and J2, 120VAC~ terminals of the board. 2. Connect a voltmeter and the LED string at J3 (LED+) and J4 (LED-) connectors, as shown in Figure 2-1. The LED string can be formed with 70 to 90 LED cells (3 LEDs in parallel), 80 mA SMD LED, 280 mW. An example is shown in Figure 2-2.

Installation and Operation 2.3 HOW DOES THE HV9805 120VAC 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 120VAC 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. EQUATION 2-1: SENSE RESISTORS RELATIONSHIP V REF , CCR = I LED RCRS Where: VREF, CCR = 1.0V (at 100% current level) ILED = LED current RCRS = Resistor's value is selected by the designer If: ILED = 90 mA Then: RCRS = 11.11 Choose: R11A = R11B = 22 = 2 x RCRS EXAMPLE 2-1: The headroom voltage is programmed to the desired level using Equation 2-2. EQUATION 2-2: THE DESIRED DC LEVEL OF HEADROOM VOLTAGE V REF , HVR = V HDC K DIV R HVB K DIV = --------------------------------------R HVB + R HVT Where: VREF, HVR = 1.25V VHDC = DC level of the headroom voltage KDIV = Attenuation of the headroom voltage divider RHVT, RHVB = Top and bottom resistor of the headroom voltage divider EXAMPLE 2-2: For: Then: VHDC = 4V KDIV = 1.25/4 = 0.3125 RHVT/RHVB = 2.2 Then: RHVB = 10 k Choose: RHVT = 22 k Therefore: 2015 Microchip Technology Inc. DS40001785A-page 17 HV9805 120VAC Off-Line LED Driver Evaluation Board User's Guide 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 an 80 LEDs string is used, a forward voltage drop on each LED of 3V is assumed. Then, the Bus Voltage level will be: VDC = 80 x 3 + VHDC = 240 + 4 = 244VDC Note: In order to have a good valley detection, choose an LED string voltage bigger by 20 to 30V than the peak input voltage (which is usually 138VAC). In this condition, the minimum LED load voltage is VLED MIN = 20 + 1.41 x 138 = 215VDC 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. EQUATION 2-3: THE POWER DISSIPATION OF THE LED CURRENT REGULATOR P DIS = ILED V HDC Where: PDIS = Power dissipation of the current LED regulator ILED = LED current VHDC = DC level of the headroom voltage PDIS = 0.090A x 4V= 0.36W The output voltage of the control amplifier provides the on-time reference for the boost converter control circuitry, according to Equation 2-4. EQUATION 2-4: THE ON-TIME REFERENCE FOR THE BOOST CONVERTER CONTROL (TON) T ON = K HVR V HVR Where: DS40001785A-page 18 TON = On-time reference signal from the headroom voltage regulator KHVR = Gain of the on-time modulator VHVR = 5V KHVR = 2.2 s/V TON = 5 x 2.2 s = 11 s 2015 Microchip Technology Inc. Installation and Operation 2.4 BOARD TESTING, TEST POINTS WAVEFORMS AND OVERALL MEASURED PARAMETERS 2.4.1 Board Testing To start testing the evaluation board follow the next steps: 1. Power the board at 120VAC. 2. Check that the voltmeter indicates the LED load voltage (do not overcome 270VDC). 3. With a power supply of 120VAC, verify whether 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 100VAC and verify whether the output current on the LED side stays regulated (IOUT ~90 mA). 5. Set the power supply to 150VAC and verify whether the output current on the LED side stays regulated (IOUT ~90 mA). Also, check that the voltage stays regulated on V2, near the value 240V. 2.4.2 Test Points Waveforms The board has several test points that help engineers to analyze the switch node's waveforms of HV9805 device output: TABLE 2-1: TEST POINTS Test Point TP1 Description Boost inductor (L3) voltage TP2 Rectified line voltage VDC TP3 Bus voltage sense (BVS pin voltage) TP4 (SW) The voltage on switching node (DRV pin) of the HV9805 device TP5 Inductor current sense voltage TP6 VDD voltage on IC (VDD pin voltage), (6.5 to 8 V) TP7 Gate control voltage (CRG pin) of the linear regulator TP8 The LED current sense (CRS pin) TP10 GND TP11 - TP12 LED string voltage TP13 High-voltage sense (HVS pin voltage) The regulated headroom voltage is approximately 8V, in order to reduce the losses on the linear regulator. 2015 Microchip Technology Inc.
