If you are looking to build a "better" converter in terms of size, look into the family. These chips integrate Gallium Nitride (GaN) transistors. Using the specific design software for VIPerGaN allows you to design ultra-small chargers and adapters that run much cooler than traditional silicon-based flybacks. Tips for a "Better" Flyback Design
Choose between fixed-frequency controllers (such as VIPer16 or VIPer26) or quasi-resonant controllers (such as VIPerPlus or VIPer0P) depending on standby power targets.
While SPICE simulation is powerful, specialized design software like or legacy VIPer Design Software (if available) offers specific advantages: A. Accelerated Design Time
