    產(chǎn)品信息

    The NCP4355 is a secondary side SMPS controller designed for use in applications which require extremely low no load power consumption. The device is capable of detecting no load conditions and entering the power supply into a low consumption OFF mode. During OFF mode, the primary side controller is turned off and energy is provided by the output capacitors thus eliminating the power consumption required to maintain regulation. During OFF mode, the output voltage relaxes and is allowed to decrease to an adjustable level. Once more energy is required, the NCP4355 automatically restarts the primary side controller by ONOFF current that flows through ONOFF optocoupler. The NCP4355 controls the primary controller with an Active ON signal, meaning that it only drives optocoupler current during ON mode to minimize consumption during OFF mode.

      NCP4355CDR2GONNCP4355 是一款輔助側(cè) SMPS 控制器，用于需要極低無負(fù)載功耗的應(yīng)用。此器件能夠檢測無負(fù)載條件，并讓電源進(jìn)入低功耗關(guān)閉模式。在關(guān)閉模式下，初級側(cè)控制器關(guān)閉，能量由輸出電容提供，因而無需耗費(fèi)電力來保持調(diào)節(jié)。在關(guān)閉模式下，輸出電壓松弛，可降至可調(diào)電平。需要更多能量時，NCP4355 通過流經(jīng) ONOFF 光耦合器的 ONOFF 電流自動重新啟動初級側(cè)控制器。NCP4355 用有效導(dǎo)通信號控制主控制器，即只在打開模式下驅(qū)動光耦合器電流，從而最大限度地降低關(guān)閉模式時的功耗。 立即購買
