Maxim Introduces New 3.3V Synchronous DC-DC Regulator That Integrates MOSFETs

Maxim Integrated Products introduced the MAX15040, a low-voltage (2.4 to 3.6V), synchronous switching regulator in a 2 x 2mm 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 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 to +85° extended temperature range. Prices start at $2.17 (1000-up, FOB USA).
