1 Introduction/ 简介 The TEA1723 is a small and low cost module Switched Mode Power Supply (SMPS)controller IC for 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 highefficiency over the entire load range with ultra-low power consumption in the noload 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. At higher power levels, a frequency and current control mode is used. It operates with Burst mode control at low power levels and no-load condition. The burst mode minimizes audible noise and provides an energy saver state which reduces the power consumption in no-load condition. The Burst mode frequency of 905 Hz enables no-load power consumption < 25 mw at 230 V (AC) mains input. TEA1723 是一款小型低成本离线式开关电源控制 IC, 内置 700V MOSFET 开关管, 输出功率可达 11W, 全负载范围内效率可做到最佳, 空载功率非常低 启动 PIN 直接到主电源回路, 可节省分压泄放电阻, 以降低成本及空载功耗 TEA1723 在负载电流范围内为一个稳压源 ; 在电流递加到引起输出电压变低的情况下, 作为一个电流源, 以防止电流太大, 引起严重故障 使用 TEA1723 可达到较低的成本较少的元件数量 TEA1723 为原边反馈控制器, 可节省副边反馈回路以简化设计 在高 Levels 电源设计要求下,TEA1723 具有 Burst 工作模式, 在空载时, 可减小噪声及功耗 3
