Texas Instruments UCC28910D

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

Overview

TopologyFlyback Converter
Input voltage108-305 V
Output 13.6 V / 0 A
IC revisionB

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.
