Maxim unveils 3/8/12/18A DC/DC regulators

Maxim Integrated Products Inc. has uncloaked what it dubs as the industry's smallest current-mode, synchronous DC/DC converters that deliver up to 3, 8, 12 and 18A, respectively, of output current. The MAX15058, MAX15108, MAX15112 and MAX15118 integrate MOSFETs to simplify designs and offer the highest efficiency in a tiny wafer-level package (WLP), added the company.

Operating in fixed pulse-width modulation (PWM), the regulators are geared for telecom, networking, server and base-station applications. Configured in a pulse-skip mode, they will reduce power during light load conditions found in notebook and single-cell battery applications.

The MAX15058, MAX15112 and MAX15118 deliver up to 94 percent and the MAX15108 delivers up to 95 percent conversion efficiency at full load. This reduces overall power loss in the system, indicated Maxim.

The MAX15058, MAX15108, MAX15112 and MAX15118 operate from a 2.7-5.5V input voltage and provide one percent output voltage accuracy over load, line and temperature. The devices are fully specified over the -40°C to 85°C extended temperature range. The regulators are available in several sizes of WLP packages and prices start at $1.76.
