Description
- TIDA-00628, Snubber less, Non-Isolated AC/DC Flyback Converter Reference Design with Simplified Transformer. TIDA-00628 is a 15V/6.5W non-isolated, single output, AC/DC Flyback power supply that is capable of operating from wide input voltage ranging from 85Vac to 440Vac. This design demonstrates 2 key features: the elimination of snubber components enabled by use of a high-voltage bipolar transistor and simplified transformer design with no need for an auxiliary winding. Low system parts count and built in advanced protection features result in a cost-effective solution for electricity meters and industrial designs
