●Overview
●The TEA1723 is a small and low cost module Switched Mode Power Supply (SMPS) controller IC for low power applications (up to 11 W) and operates directly from the rectified universal mains input. The device includes a high voltage power switch (700 V) and has been optimized for flyback converter topologies to provide high-efficiency over the entire load range with ultra-low power consumption in the no-load condition. It provides a circuit for start-up directly from the rectified mains voltage without any external bleeder circuits. The Burst mode frequency of 430 Hz enables no-load power consumption below < 12 mW at high mains input.
