Description

The MAX20414 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 (OUT2) 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 footprint. 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 either a factory-preset or resistor-adjustable output voltage on the step-down converter. The boost converter output voltage is factory-preset. Other features include soft-start, overcurrent, and over-temperature protections. This high-efficiency two-output low-voltage DC-DC converter is available in a lead(Pb)-free, 24-pin TQFN package (see the Ordering Information table for options).APPLICATIONSADASInfotainmentSOC Power
