TIDA-00583 Reference Design

Texas Instruments

5V/1.6A & 12V/10mA AC/DC Flyback PSU for E-meter Apps Optimized for Low AC Line Input Ref Design

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 265VacMulti outputs with 5V/1.6A (2.2A peak) and 12V/10mA(non-isolated)Average 4-point efficiency of 73.8% or higher72% 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
