MAX20472EVKIT#

MAX20472EVKIT# is a MAX20472 evaluation kit that demonstrates the performance of the MAX20472 and MAX20472B, which is part of the MAX2047x series of high-efficiency, low-voltage DC-DC converters. The converter ICs boost a 3V to 4V input supply to between 3.8V and 5.25V at up to 1A. The boost converters achieve ±1.5% output error overload, line, and temperature range. The IC features a 2.2MHz (2MHz for the MAX20472B) 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 or 2.0MHz 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.
