The new DOSA-2 models feature high power densities, no external tuning components (plug & play), low profiles, high efficiencies, and Land Grid Array (LGA) footprint. The converters are ideal for harsh telecom and broadcast mast-mounted applications, as well as industrial, test and measurement, routers and medical equipment.

TDK-Lambda’s DOSA-2 product line is comprised of four series with output current/power ratings as follows, iCF (3 A/16.5 W), iCG (6A/33W), iBF (12 A/66 W) and iAF (20 A/110 W). All models within these series operate with a wide input voltage range of 4.5 V to 14 V and feature adjustable output voltages from 0.7 V to 5.5 V with conversion efficiencies up to 94.5%. These miniature 2nd Generation DOSA DC-DC converters range in size from 12.2 x 12.2 x 4.45 mm (less than 0.5 square inch) to 33 x 13.46 x 7.75 mm. Optional EPC (Edge Plated Castellation) layout is also available.

Featuring fully-optimized control loops, all models within the series provide excellent transient response without external loop-tuning components (which are needed with some similar products available on the market). Remote On/Off, Remote Sense and Power Good Signal are standard. In addition, all models can operate in ambient temperatures from -40°C up to +115°C and include a three-year warranty.

These PoL converters operate at a constant switching frequency of 600kHz, which provides a low noise profile and facilitates easy EMI filtering. All models are safety approved to UL/CSA60950-1 and VDE CB scheme per IEC/EN60950-1. These DOSA-2 converters are available now in production quantities.
