TDK-Lambda expands their line of DC/DC converters for a Simplified DPA Approach

TDK-Lambda has expanded its impressive line of DC-DC converters with the introduction iQE, iQG, and iQL series of quarter brick DC/DC converters, and the iAF, iBF, iCF, and iCG series non-isolated SMT DC/DC converters to meet customers' challenges in designing a Distributed Power Architecture.

Quarter Brick DC/DC Converters

Quarter Brick converters have been designed with confined space and demanding thermal environments in mind as required in telecom, datacom, wireless, and many other applications including test and measurement, broadcast, robotics, and industrial controls. Moreover, these open-frame modules feature operating efficiencies up to 95%, 230 W per cubic inch power density, and up to 60 A of useable output current. All models include full electrical isolation up to 1500 VDC, and a fixed switching frequency that substantially reduces the potential for system level EMI issues. Metal baseplates on most models to facilitate conduction cooling when needed.

These fully regulated DC/DC converters are ideal for powering distributed, intermediate, and Advanced Telecom Computing Architecture (ATCA) bus applications. The converters adhere to a wide range of national and international safety standards, including UL60950-1, CSA22.2, and VDE CB scheme (IEC/EN60950-1). In addition, they are RoHS compliant.

2nd Generation DOSA SMT PoL Converters

Key advantages of the DOSA-2 models include high power densities; no external tuning components (plug and 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 and 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. Each operates with a wide input voltage range of either 4.5 V to 14 V or 2.4 V to 5.5 V, and features adjustable output voltages from either 0.7 V to 5.5 V, or 0.6 V to 3.63 V, with conversion efficiencies up to 97%. These miniature 2nd generation DOSA modules range in size from 12.2 mm x 12.2 mm x 4.45 mm (less than 0.5 square inch) to 33 mm x 13.46 mm x 7.75 mm. Optional LGA (Land Grid Array) SMT solder pads are available instead of the standard EPC pads.
