NXP TEA1723FT/N1,118

非隔离8.5V ~ 20V11 W

Overview

The TEA1723FT/N1 is a Switched Mode Power Supply (SMPS) Controller IC for power applications and operates directly from the rectified universal mains input. The device includes a high voltage power switch and has been optimized for fly-back 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 converter operates as a regulated voltage source from no-load up to the maximum output current and operates as current source that delivers the maximum current over a broad output voltage range. Using the TEA1723, a low power converter can be built at minimum cost and with the minimum number of external components. The controller regulates the output voltage with primary-side sensing which eliminates the need for an additional secondary feedback circuitry and simplifies the design.
