The MAX20413 is a high-efficiency, two-output, low-voltage DC-DC converter. OUT1 boosts the input supply up to 8.5V at up to 750mA, while a synchronous step-down converter operates from a 3.0V to 5.5V input voltage range and provides a 0.8V to 3.8V output voltage range at up to 3A. The boost converter achieves ±2% and the buck converter achieves ±1.5% 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 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, and make the layout a much simpler task with respect to discrete solutions.
The IC’s step-down regulator can be configured with either a factory-preset or resistor-adjustable output voltage (see the Ordering Information/Selector Guide for options). Other features include soft-start, overcurrent, and overtemperature protections.
