Evaluation Kit for the MAX20472

NDA Required. Request Full Data Sheet and Software

Description

The MAX20472 evaluation kit demonstrates the performance of the MAX20472, which

is part of the MAX20471–MAX20473 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 over load, 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 R_DS(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.
