1. general description the TEA1892ATS is a member of the new generation of synchronous rectifier (sr) controller ics for switched mode power supplies. its high level of integration allows the design of a cost-effective powe r supply with a very low number of external components. the TEA1892ATS is a controller ic dedicat ed to synchronous rectification on the secondary side of discontinuous conduction mode and quasi-resonant flyback converters. the TEA1892ATS is fabr icated in a silicon-on-insulator (soi) process. 2. features and benefits 2.1 distinctive features ? accurate synchronous rect ification functionality ? wide supply voltage range (8.5 v to 38 v) ? high level of integration, resulting in a very low external component count ? high driver output voltage of 10 v to drive all mosfet brands to the lowest r dson ? selectable regulation le vel for driver stage 2.2 green features ? low current consumption ? high system efficiency from no-load to full load 2.3 protection features ? undervoltage protection (uvp) 3. applications ? the TEA1892ATS is intended for adapters. the device can also be used in all other discontinuous conduction mode systems and quasi-resonant flyback systems that demand a highly efficient and cost-effective solution.
