5V/1.6A & 12V/10mA AC/DC Flyback PSU for E-meter Apps Optimized for Low AC Line Input Ref Design
TIDA-00583.2: The TIDA-00583 design 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.
Universal AC Input, 12Vout 0.5A Power Supply with Low Standby Power Reference Design
PMP4447: The PMP4447 is a power reference design with a universal AC input and a DC isolated output of 12V at 0.5A. It implements a high efficiency primary side controller UCC28910 which has an integrated 700V high voltage MOSFET. Additionally this reference design was characterized with the high efficiency DC/DC converter TPS5405 to generate a 5V output. The full system achieves <100mW in standby mode. The board measures 36mmX30mmX15mm. The PMP4447 is fully tested and passes EMC (CE) requirements.
