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
