Smallest 4A Switching Regulator Simplifies Designs and Improves Reliability

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

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. The Company was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers' products. To date, it has developed over 6400 products serving the industrial, communications, consumer, and computing markets.
