AN1631 Using PSPICE to Analyze Performance of Power MOSFETs in Step-Down, Switching Regulators Employing Synchronous Rectification
Prepared by: Rick Honda and Scott Deuty Motorola, Inc.
INTRODUCTION
This paper will describe an easy method to analyze performance of various power MOSFETs in step down switching regulators using the PSPICE circuit analysis tool. A comparison will be made between circuit simulation results and the measured performance described in Motorola Application Note AN1520. The utility of having a model which closely simulates switching performance is that different MOSFETs and diodes can be used in the model and comparisons can be made for proper performance vs. price, size, etc. prior to buildi
