Circuit Designs presents tips and tricks for solving problems of interest to power supply designers. Here is where PI Engineers turn their training and experience into practical circuit designs that can employed to quickly and straightforwardly address problems of the sort that working designers often encounter.

• Ferrite Magamp on Flyback Power Supply
• Over Current Protection Using an Existing Crowbar Circuit
• Active Shunt Regulator and Pre-load
• A High-Voltage Input Switching Power Supply using StackFET™
• Designing a Forward Converter Using TOPSwitch^®-GX
• Simplify and Reduce the Cost of EMI Filter Circuitry in AC/DC Converters
• Floating Constant Current Source Allows Ultra-Wide Input Voltage Range
• Low Cost Output Disable with Soft Start Kills Current Spike
