The MAX20415 is a high-efficiency, dual-output, low-voltage DC-DC converter. The 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 3A. The buck converters achieve ±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 use of all-ceramic capacitors, minimizing the total solution footprint. Programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low R_DS(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 or resistor-adjustable output voltages. Other features include soft-start, over-current protection, pin diagnostics, and overtemperature protections. The MAX20415 is available in a lead(Pb)-free, 24-pin TQFN package (see the Ordering Information/Selector Guide for available options).

Product Details

The MAX20415 evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the MAX20415 highefficiency, low-voltage DC-DC converter. The 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 3A. The 2.2MHz switching-frequency operation allows for the use of all-ceramic capacitors and minimizes external components.

The EV kit features two on/off jumper controls and two reset outputs to indicate output status for each converter. It also provides a sync input to select the operating mode (PWM, skip, or external synchronization), and a PV_OV output as an input power-good indicator.
