Analog Devices / Maxim Integrated MAX20096EVSYS Evaluation Kit
Analog Devices MAX20096EVSYS Evaluation Kit is used to evaluate, control, and configure the MAX20096. The MAX20096 components are dual-channel, high-voltage, synchronous N-channel high-current buck LED drivers that use a proprietary average current-mode-control scheme to regulate the inductor current. The MAX20096 is available in a space-saving thermally enhanced (5mm x 5mm), 32-pin side-wettable TQFN package and is specified to operate over a -40°C to +125°C automotive temperature range.
The Analog Devices MAX20096EVSYS Evaluation Kit operates from a 4.5VDC to 65VDC supply voltage and is configured to deliver up to 3A in each string of LEDs for both channels. The total voltage of the string can vary from 3V to 55V. The LED string anode should be connected to the LED+ terminal, and the cathode should be connected to PGND.
