New Miniature Step-up Transformers are Ideal for Energy Harvesting Applications

(PresseBox) (Cary, IL, USA, ) Coilcraft's new 6x6 mm LPR6235 Series coupled inductors can be used as step-up or flyback transformers in DC-DC converters or as autotransformers. They are ideal for voltage step-up in energy harvesting applications and have been selected by Linear Technology for their LTC3108 and LTC3109 Ultralow Voltage Step-Up Converter and Power Managers.

LPR6235These compact, shielded parts measure just 6mm square by 3.5mm high. They feature an excellent coupling coefficient (k = 0.95) and are available with five turns ratios from 1:10 to 1:100 for a variety of voltage step-up and step-down applications. They offer 300V winding-to-winding isolation and their combination of high Isat and low DCR provides high efficiency and excellent current handling in a rugged, low-cost design. Coilcraft also offer an even smaller LPR 4012 Series transformer that measures a mere 4mm square by 1.1mm high.

Both versions are RoHS compliant and offer a maximum reflow temperature of 260°C. They feature silver-palladium-platinum-glass frit terminations. COTS Plus tin-silver-copper and tin-lead terminations are also available.

As with all Coilcraft parts, free evaluation samples and complete technical specifications are available online at http://www.coilcraft.com/lpr6235.cfm and http://www.coilcraft.com/lpr4012.cfm respectively.

Parts are available from stock and can be ordered on-line at buy.coilcraft.com or by calling a local Coilcraft sales office.
