Analog Devices / Maxim Integrated MAX2047xEVKIT Evaluation Kits

Analog Devices Inc. MAX2047xEVKIT Evaluation Kits demonstrate the performance of the MAX20471 or MAX20472. The MAX20471–MAX20473 devices are a series of high-efficiency, low-voltage DC-DC converters. The converter ICs boost a 3.0V to 4.0V input supply to between 3.8V and 5.25V at up to 500mA. 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. It also has 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 compared to discrete solutions. The regulator includes True Shutdown™, soft-start, overcurrent, and overtemperature protection.
