NXP Semiconductors TEA1721BT
The TEA1721 is a small and low cost module Switched Mode Power Supply (SMPS) controller IC for low power applications (up to 5 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.FEATURES AND BENEFITS
