Save Weeks of Simulation, Comparison, Analysis on PFC, PSFB + SR Discretes
The ability to dramatically accelerate discrete component selection and design for popular 100 W to 3,000 W power
supplies is now available with Fairchild’s Power Supply WebDesigner (PSW). Our power factor and phase-shifted
power train modules automatically select design-appropriate devices such as MOSFET, IGBT, rectifier and diode; display
efficiency and power loss analysis; present a summary and BOM report; all based on your electrical and mechanical input specifications. Power engineers can then optimize component selections for their particular design by varying
Fairchild device combinations as the software program quickly displays the new performance analyses and output results. Weeks of bench time can now be accomplished in a matter of minutes, at no expense.

PSW Power Train Discrete represents the fastest, easiest, most accurate way to implement discrete circuits for power factor correction and phase-shifted full bridge designs. Specifically this free online tool:
•Provides Power Factor Correction (PFC) and/or
Phase-Shifted Full Bridge (PFSB) with Synchronous Rectification (SR) power train selection and analysis,in separate modules
•Is optimized for use with UCC28950 and UCC3895 controllers where PFSB + SR is required
•Delivers approximately 2 percent difference to line and load conditions verified to real-world test results
•Eliminates the need to solder, de-solder, measure and document several device combinations on the bench
•Takes user input to automatically trigger an optimum set of power discrete, transformer and inductor design values
•Displays a dashboard of the converter’s system and device power loss, device junction temperature and further fine tuning over operating conditions
•Supports the ability to optimize final performance by selecting Fairchild’s leading MOSFET and IGBT technologies, including SuperFET®, SuperFET® II, SupreMOS®, PowerTrench® and Field Stop IGBT
•Automatically generates a BOM which can be used for instant procurement; allows users to confidentially save results for future reference or sharing
