TDK-Lambda SMT 3A to 20A DC-DC Converters
|TDK-Lambda announces the iCF, iCG, iBF and iAF series of non-isolated SMT DC-DC Converters that comply with the latest 2nd Generation DOSA standards for Point-of-Load (PoL) converters. Key features of the new DOSA-2 models include: High Power densities, no external tuning components (plug & play), low profiles, high efficiencies, and Land Grid Array (LGA) footprint. These converters are ideal for harsh telecom and broadcast mast-mounted applications, as well as industrial, test & 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 (3A/16.5W), iCG (6A/33W), iBF (12A/66W) and iAF (20A/110W). All models within these series operate with a wide input voltage range of 4.5V - 14V and feature adjustable output voltages from 0.7V - 5.5V 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) - 33 x 13.46 x 7.75 mm. Optional EPC (Edge Plated Castellation) layout is also available.
Featuring fully-optimised 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 degC up to +115 degC and include a 3-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.
