Analog Devices / Maxim Integrated MAX20474EVKIT Converter Evaluation Kit
Analog Devices MAX20474EVKIT Converter Evaluation Kit evaluates the performance of the MAX20474 synchronous boost converter. The MAX20474 is a high-efficiency DC-DC converter that boosts a 3.0V to 5.5V input supply from 6V to 18V at a 1A load. The boost converter achieves ±1.5% output error over load, line, and temperature range. The Analog Devices MAX20474EVKIT allows for the typical device performance evaluation with fixed output or adjustable output voltage. With the installation of R2, it is also possible to evaluate the closed-loop stability performance if a network analyzer is available.
