Document 889-1 Coupled Inductors MSD1583 For Flyback, SEPIC, Zeta and other Applications Excellent coupling coefficient (k ≥ 0.98) and 500 Vrms isolation makes the MSD1583 series of coupled inductors ideal for use in a variety of circuits including flyback, multioutput buck, SEPIC and Zeta. These parts provide high inductance, high efficiency and excellent current handling. In SEPIC topologies, the required inductance for each winding is half the value needed for two separate inductors, allowing selection of a part with lower DCR and higher current handling. + + D L1 C L2 VOUT C VIN – SW – Typical Flyback Converter L2 0.590 ±0.020 15,0 ±0,5 0.590 ±0.020 15,0 ±0,5 L1 D SW – Typical Buck Converter with auxiliary output D + L1 VIN 0.220 5,6 C 2 1 1 0.126 3,2 L1 3 2 1 3 4 0.311 Recommended 7,9 Land Pattern 0.091 2,3 L2 C VOUT – Typical SEPIC schematic 2 L2 4 + + VIN 0.165 4,2 – L2 C1 Q 0.075 1,9 0.146 3,7 + C1 Q – 4 VOUT C – Internal code 3 AUX + VIN 0.339 max 8,60 0.331 8,4 C + Dash number X + VOUT – Dot indicates pin1 123E D L1 C D Typical Zeta schematic C VOUT – If board traces are run in these areas, consider masking them to prevent shorting.

Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value. 3. DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value. 4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
