TEA1721AT/N1,118 NXP AC-DC Controller | 7-SOIC | 65kHz, 730V Startup

Product Overview

The TEA1721AT/N1,118 is a highly integrated Switched Mode Power Supply (SMPS) controller IC from NXP Semiconductors. It is designed for low-power AC-DC converter applications, offering a compact solution with minimal external components. The device operates at a fixed frequency of 65 kHz and features a high-voltage startup circuit (up to 730 V) for direct connection to the rectified mains. Its burst mode operation ensures low standby power consumption, making it ideal for applications requiring high efficiency across a wide load range.
