Flyback design & simulation in minutes—at no expense

Faster power supply designs—whether you are a power supply expert or not—are now a reality with Fairchild’s Power Supply WebDesigner (PSW). This online design and simulation tool takes your specifications and provides a complete Primary-Side Regulated (PSR) Flyback Converter or Secondary-Side Regulated (SSR) Flyback Converter design. You get a schematic, simulated verification, and bill of material in minutes. Fine-tune design parameters without a bench prototype, swap component choices and perform detailed simulations and analyses—all with the ability to confidentially save your design for future reference.

Primary-Side Regulated Flyback Converter Tool

Gain Confidence in Your Design Before Investing in HardwarePowerful online simulation provides any of the following in less than one minute:

Secondary-Side Regulated Flyback Convert Tool

Power Supply WebDesigner can create both PSR and SSR Flyback converter designs in two ways: •Automatic Design allows you to enter just basic system requirements and click Auto Complete; a complete schematic and BOM is created. •With the Advanced Design, you can enter more detailed system information and create a customized design. After fine-tuning your system

requirements, click on Next Step to be guided through step-by-step system specifications.

Measure your design performance with PSW Bode plots as well as steady state and transient wave forms---so it will work the first time. And your complete energy-efficient flyback converter design is complete in minutes, as opposed to weeks. Save engineering time and costs with Power Supply WebDesigner-—without being a power expert.

When to use the Primary-Side Regulated Flyback Converter tool:• Power supply requirements of <30W • Lower system cost: no optocoupler feedback circuit

When to use the Secondary-Side Regulated Flyback Converter tool:• Power supply requirements of <100W• Higher system cost: tighter dynamic line/load response from

optocoupler feedback circuit
