Description

General part information

MAX20472B Series

The MAX20471, MAX20472, and MAX20472B are high-efficiency low-voltage DC-DC converters that boost a 3.0V to 4.0V input supply to between 3.8V and 5.25V (factory-configurable) at 500mA or 1A. The boost converters achieve ±1.5% output error over load, line, and temperature range.The devices feature a 2.2MHz (2.0MHz for MAX20472B) 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/2.0MHz 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 RDS(ON)switches improve efficiency at heavy loads, which make the layout a much simpler task with respect to discrete solutions.Other features include true shutdown, soft-start, overcurrent, and overtemperature protections.ApplicationsAutomotive CAN TransceiversAutomotive Point of Load
