Analog Devices / Maxim Integrated MAX20457 Evaluation Kit

Analog Devices Inc. MAX20457 Evaluation Kit is a fully assembled and tested application circuit that simplifies the MAX20457 2.1MHz Buck Converters evaluation. ADI MAX20457 operates with an input voltage supply from 3.5V to 36V and can operate in dropout conditions by running at a 95% duty cycle. All installed components are rated for the automotive temperature range, and various test points and jumpers are included.

Analog Devices MAX20457 Evaluation Kit comes with the MAX20457ATIE/VY+ installed (5V, 3.3V, 2.1MHz). The Kit also can be used to evaluate other MAX20457 variants with minimal component changes.
