Coupled Inductors – LPD3015 For SEPIC and other
Applications
At only 1.4 mm high and 3 mm square, the LPD3015
is Coilcraft’s smallest shielded coupled inductor. It is
ideal for use in a variety of circuits including flyback,
multi-output buck and SEPIC.
These inductors provide high inductance, high efficiency
and excellent current handling in a rugged, low cost part.
They can also be used as two single inductors connected
in series or parallel or as a common mode choke.
