Beschreibung

http://www.ti.com/tool/TIDA-00628TIDA-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 (1) the elimination of snubber components enabled by use of a high-voltage bipolar transistor and (2) simplified transformer design with no need for an auxilliary winding. Low system parts count and built in advanced protection features result in a cost-effective solution for electricity meters and industrial designs.

Eigenschaften

Input voltage up to 440Vrms, 15V/6.5W outputNo snubber - reduces BoM count and PCB areaBJT switch to reduce system costNon Isolated output allows simplified transformer with no auxilliary windingTypical efficiency of 80% at 230V, 6.5WCompliant with Conducted Emissions: CISPR 22, Class B

Typische Anwendungen

  • Bias supplies in 3 phase systems
  • Industrial power supplies
