MAX15040: 4A switching regulator simplifies designs and improves reliability

The MAX15040 operates from a fixed 1MHz switching frequency to further reduce total solution size, as it allows all-ceramic-capacitor designs. Offering efficiencies up to 94% at full load current (4A), this point-of-load regulator minimizes power loss in applications such as telecom, networking, and server equipment.

Other features include an enable input and power-good indicator for power sequencing, adjustable soft-start for controlled turn on, and the ability to safely start up into a prebiased output.

The MAX15040 provides ±1% output-voltage accuracy over temperature and is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range.
