Document 820-1 For Flyback, SEPIC, Zeta Coupled Inductors LPD5010 and other Applications The LPD5010 coupled miniature shielded inductors are mere 1 mm high and 5 mm square. They are ideal for use in a variety of circuits including flyback, multi-output buck, SEPIC and Zeta. These inductors provide high inductance, high efficiency and excellent current handling in a rugged, low cost part. They can also be used as two single inductors connected in series or parallel or as a common mode choke. + + D C V L1 L2 OUT C V IN SW Typical Flyback Converter + D V OUT C AUX L2 0.189 0.003 ++ 4,80 0,076 Dot indicates pin 1 L1 V V C OUT D IN SW 14 0.189 0.003 Typical Buck Converter with auxiliary output 4,80 0,076 XXXX 23 D ++ L1 C1 Dash Internal Recommended number code V C Q L2 C V OUT IN LandPattern 0.138 3,50 0.090 Typical SEPIC schematic 0.035 0.004 2,30 0,9 0,1 45 typ ++ L2 C1 0.134 0.090 0.197 0.030 Q 3,40 2,30 5,00 V 0,75 D CC OUT V L1 IN 0.060 0.060 Typical Zeta schematic 1,52 1,50 0.134 3,40 0.197 1 4 5,00 L1 L2 inches Dimensions are in mm 3 2 Document 820-1 Revised 01/13/12 US +1-847-639-6400 sales coilcraft.com UK +44-1236-730595 sales coilcraft-europe.com Coilcraft Inc. 2014 This product may not be used in medical or high Taiwan +886-2-2264 3646 sales coilcraft.com.tw risk applications without prior Coilcraft approval.
