Utterly superb collection of papers relating to magnetics design. Do not be fooled by the claim that the zip file contains all the other files. Do be annoyed by the amazingly brain dead way the zip file is structured. Do be forever grateful to TI for this fantastic resource. http://focus.ti.com/docs/training/catalog/events/event.jhtml?sku=3DSEM40101= 4 Russell McMahon ____________________________ This is NOT what you'll see but gives you an idea of what's there Coupled filter inductors in multi output buck regulators slup082a (1)_q91.pdf Magnetic amplifier control slup129.pdf Reference design section slup128.pdf Intoduction and basic magnetics slup123.pdf Magnetic core characteristics slup124.pdf Windings slup125.pdf Power transformer design slup126.pdf Inductor and flyback transformer design slup127.pdf The effects of leakage inductance on switching power supply performance slup199.pdf Inductor and Flyback Transformer Design.url Introduction and Basic Magnetics (Magnetics Design for Sw.
