PI33XX-X0 Datasheet, PDF (37/42 Pages) List of Unclassifed Manufacturers – 8V to 36Vin Cool-Power ZVS B uck Regulator Family

thermal operation is limited by either the MOSFETs
or inductor depending upon line and load conditions.
Thermal measurements were made using a standard
PI33XX Evaluation board which is 3x4 inches in area
and uses 4-layer, 2oz copper. Thermal
measurements were made on the three main power
devices, the two internal MOSFETs and the external
inductor, with air flows of 0, 200, and 400 LFM.
