DS50002940A-page 8 2020 Microchip Technology Inc. HV96001 OFFLINE LED DRIVER EVALUATION BOARD USER’S GUIDE Chapter 1. Quick Start Instruction
1.1 INTRODUCTION This chapter provides an overview of the HV96001 Offline LED Driver Evaluation Board and covers the following topics: • HV96001 Device – Short Overview • HV96001 Device – Key Features • Evaluation Design Kit Contents
1.2 HV96001 DEVICE – SHORT OVERVIEW The HV96001 is an LED driver device that targets offline lighting applications requiring wide range dimming capability. The device provides both linear and Pulse Width Modulation (PWM) dimming capability, the PWM dimming capability having particularly wide dimming range. The driver IC is adapted to a system that consists of: • a flyback converter, for converting AC power to DC power with high power factor and with galvanic isolation, the output voltage being regulated for optimizing system efficiency, • a boost converter, for boosting the flyback converter output voltage to the LED load voltage with near zero ripple for a flicker free LED current, and • a linear load switch, for PWM dimming the LED current with a wide range of the PWM duty.
1.3 HV96001 DEVICE – KEY FEATURES • Linear (analog) dimming with wide range of the amplitude control of the LED current • PWM (digital) dimming, dims down to 0.01% and lower, with PWM pulse width down to 150 ns • Flyback converter control with automatic output voltage adjustment for maintaining high system efficiency • Boost converter with near zero output voltage ripple for ripple free LED current
•VDD internal regulator with 60V input voltage capability/5V output voltage, 10 mA drive for supplying external loads • Fault recovery with auto-retry delay
• Undervoltage detection of VDD voltage set using timing capacitor and for supply voltage (flyback output voltage) • Overvoltage detection of the LED load voltage (boost output voltage) • Overcurrent detection of the load switch current • Stuck-at-zero detection of the DIM input signal

DS50002940A-page 10 2020 Microchip Technology Inc. HV96001 OFFLINE LED DRIVER EVALUATION BOARD USER’S GUIDE Chapter 2. Installation and Operation
2.1 GETTING STARTED HV96001 Offline LED Driver Evaluation Board is fully assembled and tested to evaluate and demonstrate the HV96001 LED driver. In the primary side, the flyback converter has implemented an active Power Factor Correction (PFC) control algorithm by a PIC controller that commands the switching sequence in such a manner that the input current follows the input voltage envelope, as shown in Figure C-1. Therefore, the power factor of the application is PF > 0.9, for the entire input voltage range. The power factor value (PF) should be tuned by using R52 potentiometer according to the rated power of the LED load used. The tuning should be done in no dimming conditions. For example, to obtain a power factor PF over 0.9 for a 42W LED load, the value for the R52 resistor will be set to 750Ω. Check if mechanical jumper JP1 (provided) is mounted on the J11 connector.
2.1.1 Powering the HV96001 230VAC Offline 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 80 to 265VAC. 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 LED Load is not provided but the output of the driver can supply a LED load of 20-45 VDC rated and current up to 0.8A. Do not use a LED load bigger than 45V since the overvoltage protection, OVP, would became active, causing light interruption at the output.

2.2 SETUP/CONFIGURATION The output voltage and current delivered by the HV96001 Offline LED Driver Evaluation Board can be set by using the rotary encoder E1. After the board is supplied with 230VAC the initial PWM dimming value is 50% and current reference limit LCR is 200 mV. To increase the PWM duty cycle the encoder must be rotated to the right (clockwise) and to decrease the encoder must be rotated to the left (counter-clockwise). The actual value of the PWM percent reference will be displayed on the LCD from the secondary side of the flyback, in the first information row, as in the picture below. The value of 0.15% is given by the minimum voltage over the UVLO protection performed by the HV96001 for the input voltage. When the PWM is getting lower than 15%, the LCR is decreasing linearly to avoid big currents spikes. For the current increase or decrease, the encoder must be pressed to activate the switch button and to be rotated to the left or to the right in a similar way as for PWM dimming variation described above. The maximum value of the PWM dimming is 100% and of the current reference (LCR) is 400 mV. The maximum LCR value of 400 mV is corresponding to a 0.7-0.8A current through the LED Load.
FIGURE 2-2: Rotary Encoder and LCD Used to Display Parameters. The LED Load current limit is calculated using the following formula:
EQUATION 2-1:
VLCR ILED = ------RLCS
Where:
VLCR =400mV RLCS = 0.524Ω (R32 II R41 II R45) R32 = 1Ω R41 = 2.2Ω R45 = 2.2Ω
Resulting ILED = 0.76A
The board has a mikroBus™ connector to allow multi-protocol communication by using different click boards (produced by MikroElektronika Serbia, not provided with this kit). The firmware was developed for the RN4871 Bluetooth® module click board. The click board should be plugged in the mikroBus connector before the main board is supplied from the grid. After the board is supplied, the Bluetooth module is configured and can be used with the provided Android application.
