TPS92310DGSR/NOPB Off-Line Primary Side Sensing Controller With PFC MSOP8 spot stock

Product Descriptions

The  TPS92310  is  an  off-line  controller  specifically designed  to  drive   high   power   LEDs  for   lighting applications. With the primary side sensing, constant on-time and quasi-resonant switching techniques, the TPS92310   application   circuit   gives   high   Power Factor,  good  EMI  performance  and  high  system efficiency.   Also,   using   this   device,   low   external component   count   application   solutions   can   be designed easily. Power Factor Correction is inherent if the TPS92310 is operated in the constant on-time mode   with   an   adaptive   algorithm.   The   control algorithm  of  TPS92310  adjusts  the  on-time  with reference to the  primary side  inductor peak current and    secondary    side    inductor    discharge    time dynamically, the response time of which is set by an external capacitor. Also, minimized EMI and switching loss is achieved with quasi-resonant switching. Other supervisory features of the TPS92310 include cycleby-cycle  primary  side  inductor  current  limit,  VCC under-voltage lockout, output over-voltage protection and thermal shutdown. The TPS92310 is available in the VSSOP-10 package.
