Texas Instruments

108VAC-305VAC Input: 3.6V/5mA Flyback Reference Design

Description

This low power flyback supply is designed to minimize the total input current while supplying a low power 3.6V/5mA output.  The output is functionally isolated from the input: but not for safety.  The physical size is minimized by using the UCC28910 controller with integrated high-voltage MOSFET and primary-side regulation.

Features
  • Less than 500µA input current for loads less than 4mAWide 108-305VAC input rangeSmall form factor (25mm x 18mm x 20mm)Function isolationTest report available
