The MAX15040 is a low-voltage (2.4 to 3.6 V), synchronous switching regulator in a 2 x 2-mm wafer-level package (WLP). This miniature step-down regulator integrates MOSFETs to simplify design, minimize EMI, improve reliability, and save board space.
The MAX15040 operates from a fixed 1MHz switching frequency to further reduce total size, as it allows all-ceramic-capacitor designs. Offering efficiencies up to 94% at full load current (4 A), 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° to 85° C extended temperature range.
