Coupled Inductors – LPD3015 For SEPIC and other
Applications
• Only 1.4 mm high and 3 mm square
• Ideal for use in flyback, multi-output buck, SEPIC and Zeta
applications.
• High inductance, high efficiency and excellent current
handling
• Can also be used as two single inductors connected in
series or parallel or as a common mode choke.
