Providing a perfect flyback design within minutes
Fairchild Semiconductor's Web-based Design and Simulation Tool

Based on the specifications provided by the user, circuit diagrams, and verification results through simulation,
BOM, seller search, and order provision

The work of designers facing the challenge of designing flyback circuits for application power supply has become easier. Fairchild Semiconductor, a leading global supplier of high-performance power and mobile products, introduces Power Supply WebDesigner (PSW), an easy-to-use and powerful online simulation tool that provides “Auto Design” and “Advanced Design” like a power supply expert, without the need for traditional application notes.

PSW is an easy-to-use, powerful online design tool that offers the following advantages.

• Complete flyback design including optimized Fairchild controller and MOSFET selection
• Loop gain plot showing stability margin and steady-state and transient waveforms
• Complete BOM and Seller Parts Order
• Simulation features that help designers tune their designs without building bench prototypes

Through user-specified design inputs, the Power Supply WebDesigner Tool allows designers to select all components used in the design, including MOSFETs, diodes, transformers, snubber circuits, output filters (seconds), AC input circuit resistors, and capacitors. By providing available Fairchild component names, the Tool enables automatic design recommendations. PSW supports automatic design recommendations or allows the user to evaluate their own component selections.

Using this tool, designers can use default recommended values or dedicate time to optimizing details critical to their unique design requirements. Designers can quickly and accurately evaluate design performance and continuously improve their design choices. This tool also enables detailed analysis and provides time to gain insights into how their designs perform.

This tool simulates Bode plots, steady-state, and transient waveform shapes. This tool allows designers to see if their designs can function properly, so they can be confident that it will work well from the start. The PSW tool enables designers to respond to high-speed rotation requests in power converter designs without building bench prototypes.

Once the design is complete, a Bill of Materials (BOM) is generated to save time on the PSW document or to procure other parts; after sending it to their procurement department, the parts can be procured immediately online. Additionally, they can save their design for future reference and share it with other engineers.

Using the Power Supply WebDesigner Tool provides inexperienced designers with fast design capabilities, while allowing experienced designers to consider their requirements and further optimize their designs.
