Evaluates: MAX20096 MAX20096 Evaluation Kit/ MAX20096 Evaluation System General Description Quick Start The MAX20096 evaluation kit (EV kit) provides a proven Required Equipment design to evaluate the MAX20096 dual-channel syn- MAX20096 EV kit chronous buck, high-brightness LED controller with and MINIQUSB interface board and USB cable without SPI interface for high-power HB LED drivers. The EV kit is set up as a dual-buck LED driver and 5V to 65V, 4A DC power supply operates from a 4.5V to 65V DC supply voltage. The EV Four digital voltmeters kit is configured to deliver up to 3A in each string of LEDs Two series-connected HB LED strings rated to no less for both channels. The total voltage of the string can vary than 4A from 3V to 55V. The anode of the LED string should be connected to the LED+ terminal the cathode should be Two current probes to measure the HB LED current connected to PGND. Small flat-blade screwdriver to turn the potentiometer wiper adjustment pin Benefits and Features Note: In the following sections, software-related items are 4.5V to 65V Input Voltage identified by bolding. Text in bold refers to items directly Drives 116 LEDs in Each of the Dual Channels from the EV kit software. Text in bold and underlined 0A to 3A LED Current refers to items from the Windows operating system. Demonstrates SPI Interface Capability Procedure Demonstrates PWM Dimming and Analog Dimming 1) Visit www.maximintegrated/evkitsoftware to Using the SPI Interface download the latest version of the EV kit software, MAX20096EVKit.exe. Demonstrates LED Open/Short Faults Monitoring Using the SPI Interface 2) Install the EV kit software GUI on your PC by run- ning the MAX20096EVKit.exe program. The EV kit Monitors the LED Current Using the Graphical User software application will be installed with the required Interface (GUI) MINIQUSB drivers. Proven PCB and Thermal Design 3) Connect the MINIQUSB board to J7 and J14 on the Fully Assembled and Tested EV kit. 4) If connecting multiple EV kits in a daisy-chain, see the Daisy-Chain Connections section.
