Maxim Integrated Products debuts the MAX15058/MAX15108/MAX15112/MAX15118, said to be the industry's smallest current-mode, synchronous DC-DC converters that deliver up to 3, 8, 12, and 18A, of output current respectively.

These DC-DC regulators integrate MOSFETs to simplify designs and provide the highest efficiency in a tiny wafer-level package (WLP), according to the company. Operating in fixed pulse-width modulation (PWM), they are targeted at 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, noted Maxim.

These DC-DC regulators are said to be highly efficient. The MAX15058/MAX15112/MAX15118 deliver up to 94 per cent and the MAX15108 delivers up to 95 per cent conversion efficiency at full load, according to the company. 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 per cent 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 Rs.87.13 ($1.76) (10,000-up, FOB USA).
