These off-the shelf parts can be used
to create thousands of configura-
tions, providing a convenient method
for designers to create custom mag-
netics. By connecting the windings
in series or parallel, the Hexa-Path
components can be configured as
inductors, coupled inductors and
transformers for use in virtually any
application: flyback, buck/boost,
push-pull, forward, full and half
bridge, Cuk, and SEPIC.

There are six different sizes avail-
able with five HP parts and five HPH
parts in each size. The HP offers
lower DCR and higher Irms ratings.
The HPH offers higher inductance and
greater energy storage capabilities.
