Description

General part information

MAX20419 Series

The MAX20419 is a high-efficiency, 3-output, low-voltage DC-DC converter IC. OUT1 boosts the input supply to 5V at up to 750mA, while two synchronous step-down converters operate from a 3.0V to 5.5V input voltage range and provide a 0.8V to 3.8V output voltage range at up to 3.6A. The boost converter achieves ±1.9% and the buck converters achieve ±1.4% output error over load, line, and temperature range. The IC features a 2.2MHz fixed-frequency pulse-width modulation (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 frequency operation allows 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 with respect to discrete solutions.The IC is offered with factory-preset output voltages (see the Ordering Information/Selector Guide for available options). Other features include soft-start, overcurrent, and overtemperature protections. The MAX20419 also has several redundancy and diagnostic features for compatibility with ASIL-rated applications.ApplicationsADASInfotainmentSOC Power
