Document 833-1 Coupled Inductors – LPD6235 ForFlybackand other Applications Tight coupling (k ≥ 0.97) makes the LPD6235 series of coupled inductors ideal for use in a variety of circuits including flyback, multi-output buck, SEPIC and Zeta. These coupled miniature shielded inductors are 3.5 mm high and 6.0 mm square. They provide high inductance, high effic.
