LTspice: Using Transformers

Gabino Alonso - Strategic Marketing Engineer Aug 25th 2011
  Transformers and coupled inductors are key components in many switching regulator designs to include flyback, forward and SEPIC converters. They perform critical function in providing an isolation barrier, enabling high step-down or step-up ratios and accommodating multiple or inverting outputs. Although it is possible ...
