Analog Devices / Maxim Integrated MAXM1790xEVKIT Evaluation Kits
Analog Devices MAXM1790xEVKIT Evaluation Kits provide a proven design to evaluate the MAXM1790x high-voltage, high-efficiency, synchronous step-down DC-DC modules. The evaluation kit is programmed to deliver 1.5V output for loads up to 300mA. The evaluation kit features an adjustable input under-voltage lockout, selectable mode, and open-drain RESET signal. The Analog Devices MAXM1790x datasheets should be read in conjunction with the evaluation kit data sheet before modifying the demo circuit.
