      APW7104 詳細介紹

      APW7104茂達電子新推出一款高效能PWM同步降壓穩壓IC。APW7104整合同步切換開關,具備更高效能并節省電路板空間,固定1.5MHz的開關切換頻率,可以在設計時使用較小型濾波組件,APW7104非常適合輕薄小巧的便攜設備。 當輸出負載過大時,APW7104內部的限流電路及與過熱保護機制啟動以保護系統,電流回授模式的架構提供快速的輸入電壓及負載瞬時響應。APW7104可提供1000mA的負載電流,操作電壓為2.5V~6.0V,APW7104提供SOT-23-5/TSOT-23-5A封裝,溫度范圍可達-40℃到+85℃。

      APW7104 is a 1.5MHz high efficiency monolithic synchronous buck regulator. Design with current mode scheme,the APW7104 is stable with ceramic output capacitor. Input voltage from 2.5V to 6.0V makes the APW7104 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable electrical devices. The internally fixed 1.5MHz operating frequency allows the using of small surface mount inductors and capacitors. The synchronous switches included inside increase the efficiency and eliminate the need of an external Schottky diode.
      The APW7104 is available in SOT-23-5/TSOT-23-5 packages。
