Description

The TIDA-00583 is a Flyback converter which can operate in very low AC line input (Minimum 45Vac) and provide a regulated, fully-isolated 5V@1.6A output for communication model of E-meter, as well as another low-power 12V non-isolated output. Featuring TIs UCC28722 PSR controller which provides accurate voltage and constant current regulation with primary-side feedback, and bipolar power switch the design eliminates opto-coupler feedback circuits and reduces system cost.

Features
  • Wide Input range from 45Vac to 265Vac
  • Multi outputs with 5V/1.6A (2.2A peak) and 12V/10mA(non-isolated)
  • Average 4-point efficiency of 73.8% or higher
  • 72% or higher efficiency at full power (5V/2.2A)
  • Low output ripple at full load, less than 150mV
  • Low system cost due to use of PSR control, BJT switch and single layer PCB
