Application examples for Hexa-Path Magnetics

Use the following examples as guides to creating custom magnetics

Inductor  Connecting windings in parallel and in series

Flyback transformer  13 Watt, 2 : 1 : 1, flyback transformer with a bias winding

Forward transformer  130 Watt, 1 : 1, two switch forward converter transformer

Half bridge forward transformer  100 Watt, 1 : 2, half bridge forward converter transformer

Gate drive transformer  1 : 1 gate drive transformer

Formulas used to calculate electrical characteristics

Connecting windings in series:

• Inductance = Inductance(table) × (number of windings)²
• DCR = DCR(table) × number of windings
• Isat = (Isat(table) × 6) ÷ number of windings connected in series
• Irms = Irms(table)

Connecting windings in parallel:

• Inductance = Inductance(table)
• DCR = 1 ÷ [number of windings × (1 ÷ DCR(table))]
• Isat = (Isat(table) × 6) ÷ number of windings connected in series
• Irms = Irms(table) × number of windings
