2-Watt DC-DC “Cube” Halves Industry-Standard Footprint

Murata Power Solutions today announced the MTU2 series of ultra-miniature surface-mounted 2W dc-dc converters from Murata Power Solutions. Believed to be the industry's smallest 2W converter and measuring just 8.2 x 8.4 x 8.5 mm with a 0.69 cm² footprint, it is 50% smaller than the current 1.67 cm² industry standard. With a typical conversion efficiency of 85% across the full load range and a power density of 3.403 Watts/cm³, the MTU2 series is available with either a single- or dual-output voltage. Input voltages cover the popular nominal inputs from 3.3- to 24-Vdc.

Output voltage options include 5-, 12-, or 24-Vdc. Dual-output models provide ±5- or ±12-Vdc. Load regulation is typically 5% better than other products available on the market, reducing the need for any additional regulation components. The MTU2 has a 1kVdc input/output galvanic isolation that helps to reduce switching noise and allows the converter to be configured to provide an isolated negative rail in systems where only positive rails exist.

Murata's product marketing manager, Ann-Marie Bayliss, comments, "The MTU2 sets a new footprint standard for 2W dc-dc converters. It has a footprint 50% smaller than the current industry standard and remains pin compatible with our 1W MTU1 surface mount converter series."

The MTU2 can operate over the full industrial temperature range from -40 to +85 degrees C. Lead-times are from stock to 10 weeks, with pricing in volume quantities in the $5.12 range.
