MAX20471EVKIT#

MAX20471EVKIT# is a MAX20471 evaluation kit that demonstrates the performance of the MAX20471, which is part of the MAX20471– MAX20473 series of high-efficiency, low-voltage DC-DC converters. The boost converters achieve ±1.5% output error overload, line and temperature range. The IC features a 2.2MHz fixed-frequency forced-PWM (FPWM) 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 enables the use of all-ceramic capacitors and minimizes external components. The programmable spread-spectrum-frequency modulation minimizes radiated electromagnetic emissions. Integrated low RDS(ON) switches improve efficiency at heavy loads and make the layout a much simpler task with respect to discrete solutions. The regulator includes True Shutdown™, soft-start, overcurrent, and overtemperature protections.
