Reference Designs
12-Watt magnetically resistant quasi-resonant flyback reference design
Texas Instruments


This reference design is a quasi-resonant flyback developed to be resistant to large magnetic fields near the transformer. It has a regulated 4 Volt output that can handle up to 2 A of current and secondary 10 V output that can handle 0.4 A.
Features
- 90 VAC to 490 VAC input to 4 V/2 A isolated outputSecondary output of 10 V/ 400 mAIron Powder Transformer for improved magnetic resistanceTopology designs to run at a low frequency to further increase magnetic resistance
