Coupled Inductors – LPR6235
For Step-Up, Resonant & Flyback Applications
Can be used as step-up or flyback transformers in DC-DC converters or as autotransformers Perfect for low
voltage step-up in energy harvesting applications Selected by Linear Technology for the LTC3108 and LTC3109 Ultralow
Voltage Step-Up Converter and Power Managers
These shielded parts are only 3.5 mm high and 6 mm square. The excellent coupling coefficient (k = 0.95) makes them ideal for use in a variety of applications. They can be used as flyback transformers and step-up pulse transformers. The high Isat and low DCR ratings of these parts provide high efficiency and excellent current handling in a rugged, low cost design. Custom inductance values and turn ratios may be available upon request.
