Application:
Transformers based on our 220 size core are designed
for a wide variety of topologies such as forward, half
and full
bridge, full bridge ZVS, and push-pull. These parts are
used in 1 kW to 3.0 kW off-line power supplies, and DC-DC
converters
delivering up to 250 amperes for a single output or 20-50
amperes for multi-output magnetics. Applications vary
from commercial and computer to military and space systems
where
high quality, reliability, repeatability and superior
thermal management are of the utmost importance. Planar
transformers
and inductors based on 220 size have small footprints
and low profiles, such as 0.600" to 0.800". Two
220 size transformers with 2kW capacity each, but without
tabs
can fit on a single credit card. Depending on the power
rating, 220 parts can run without any air flow for cooling.
In this
case they must be attached to a base plate with a controlled
temperature. Transformers operating close to or at a
maximum of specified power limit must be cooled by a combination
of conduction and air flow. Transformers can be customized,
and multi-winding coupled inductors are available. |
