2nd Generation DOSA SMT PoL Converters

TDK-Lambda has announced their new family of non-isolated SMT DC-DC converters that comply with the latest 2nd Generation DOSA standards for Point-of-Load (PoL) Converters.

Key advantages of the new DOSA-2 models include high power densities; no external tuning components (plug & play), low profiles, high efficiencies, and Edge Plated Castellation(EPC) pads for easy SMT solder joint inspections. These converters are ideal for harsh telecom/broadcast mast mounted applications, as well as industrial, test & measurement, and medical equipment.

The DOSA-2 product line is comprised of four series with output current/power ratings as follows, iCF: 3 A/16.5 W, iCG: 6 A/33 W, iBF: 12 A/66 W and the iAF: 20 A/110 W. All of these 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 97%. These miniature 2nd Generation DOSA modules 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 LGA (Land Grid Array) SMT solder pads are available instead of the standard EPC pads.
