This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.


MAXIM INTEGRATED MAX20474 Synchronous Boost Converter

The MAX20474 is a high-efficiency DC-DC converter which boosts a 3.0 to 5.5 Volts input supply to a fixed Output Selection from 6 Volts to 18 Volts at up to 1 Amp 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, or skip mode, 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.

Other features include true shutdown,  soft-start, overcurrent, and over-temperature protection making the MAX20474 a robust solution for the automotive environment.
