Analog Devices / Maxim Integrated MAX77503xEVKIT Evaluation Kits
Analog Devices MAX77503xEVKIT Evaluation Kits are fully assembled and tested PCBs that demonstrate the MAX77503 synchronous buck converter. These evaluation kits are step-down voltage regulator circuits using the MAX77503 buck converter capable of 3V to 14V input and 1.5A continuous load. The output voltage is adjustable between 0.8V and 5V with internal feedback or between 1.55V and 99% of the input voltage with the external feedback option. The Analog Devices MAX77503xEVKIT evaluation kits feature a dual-range electronic load that allows easy evaluation of loading use cases for the buck converter circuit.
