Description

General part information

MAX20474 Series

The MAX20474 is a high-efficiency DC-DC converter that boosts 3.0V to 5.5V input supply from 6V to 18V at up to 1A load. The boost converter achieves ±1.5% output error over load, line, and temperature range.The device features a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient response, as well as a pulse-frequency modulation mode (skip) for increased efficiency during light-load operation. The 2.2MHz 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 RDSONswitches improve efficiency at heavy loads and make planning the layout a much simpler task with respect to discrete solutions.Other features include True Shutdown™, soft-start, overcurrent, and overtemperature protections.ApplicationsAutomotive Point of Load
