Document 621-1 Coupled Inductors MSD7342 ForFlyback,SEPIC,Zeta and other Applications Tight coupling (k ≥ 0.97) and 200 V isolation make the MSD7342 series of coupled inductors ideal for use in a variety of circuits including flyback, multi-output buck and SEPIC. They provide high inductance, high efficiency and excellent current handling in a rugged, low cost part. Can also be used as two single inductors connected in series or parallel, as a common mode choke or as a 1 : 1 transformer. 0.72,955max 0.72,955max 123 Dot indicates pin 1 1 L1 3 2 L2 4 04.1,681max 0.150 3,8 0.028 0,7 0.091 2,3 34 21 0.063 1,6 Dimensions are in inches mm Recommended Land Pattern 0.083 2,1 If board traces are run in these areas, consider masking them to prevent shorting. 0.110 2,8 21 34 0.130 3,3 0.043 1,10 + D L1 L2 C VIN C SW – Typical Flyback Converter + VOUT – L2 D C + VOUTAUX – ++ L1 VIN SW D C VOUT –– Typical Buck Converter with auxiliary output + VIN C L1 Q C1 L2 D C + VOUT –– Typical SEPIC schematic + VIN C – Q C1 L2 L1 D C Typical Zeta schematic + VOUT – Specifications subject to change without notice.
