Description

The MAX20474 evaluation kit (EV kit) evaluates the performance of the MAX20474 synchronous boost converter.

The MAX20474 is a high-efficiency DC-DC converter which boosts a 3.0V to 5.5V input supply from 6V to 18V at up to 1A load. The boost converter achieves ±1.5% output error over load, line, and temperature range.

The device features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load transient response and a pulse-frequency modulation mode (SKIP) for increased efficiency during light load operation. The 2.2MHz frequency operation allows for the use of all ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low RDSON switches improve efficiency at heavy loads and simplifies the layout with respect to discrete solutions.

Other features include true shutdown, soft-start, and overcurrent and overtemperature protections.
