Highly efficient regulators come in small packages

Maxim Integrated Products’ newest synchronous DC-DC converters provide the highest efficiency while reducing external component count.

Maxim Integrated Products introduces the MAX15058/MAX15108/MAX15112/MAX15118, one of the industry’s smallest current-mode, synchronous DC-DC converters that deliver up to 3, 8, 12, and 18A, respectively, of output current. These DC-DC regulators integrate MOSFETs to simplify designs and provide the highest efficiency in a tiny wafer-level package (WLP). Operating in fixed pulse-width modulation (PWM), they are suitable 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.

These DC-DC regulators are highly efficient. The MAX15058/MAX15112/MAX15118 deliver up to 94% and the MAX15108 delivers up to 95% conversion efficiency at full load. This reduces overall power loss in the system.

The MAX15058/MAX15108/MAX15112/MAX15118 operate from a 2.7V to 5.5V input voltage and provide ±1% 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 (10,000-up, FOB USA).
