How to design an efficient offline auxiliary power supply workshop
 | Join ST and Würth Elektronik to learn how to design an efficient offline auxiliary power supply with low to medium output power and select the proper components |
Discover how eDesignSuite, ST’s easy-to-use on-line design tool, helps you rapidly select and determine the optimal configuration for your power management design; reducing your final cost and improving your time to market.
STMicroelectronics & Würth Elektronik invite you to this workshop that will examine the theory, components and PCB layout to ensure the best design for the following topologies:
- Low-power buck topology for mains applications
- Medium-power quasi-resonant flyback topology for power converters
Benefits you will take away
- Technical overview of buck and quasi-resonant flyback topologies
- Live session using eDesignSuite to analyze the impact of various components on circuit voltages and currents to determine the best design for your application
- Live session using an oscilloscope to observe waveforms in real-time, to study circuit voltages and currents and how they affect your application
- Tips and tricks to ensure the best PCB layout for your application
