CXDC6578

CXDC6578系列是具有所有必需激活功能的降压开关稳压器。具有良好的线路和负载调节能力,可驱动3A负载。这些设备有3.3V、5V的固定输出电压和可调输出版本。
CXDC6578系列为流行的三端线性稳压器提供了高效的替代品。它还需要最少数量的外部组件。它不仅大大减小了电路板的面积,而且还减小了散热器的尺寸,在某些情况下,不需要散热器。
在规定的输入电压和输出负载条件下,保证输出电压的±4%公差。同时,振荡器频率精度在±10%以内。包括外部关机,具有70μA(典型)备用电流。输出开关包括逐周限流,以及故障条件下完全保护的热关机

一.产品概述FmU嘉泰姆


   The CXDC6578 series are step-down switching regulators with all required active functions. It is capable of driving 3A load with excellent line and load regulations. These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version.FmU嘉泰姆

   The CXDC6578 series offers a high-efficiency replacement for popular three-terminal linear regulators. Also it requires a minimum number of external components. It substantially not only reduces the area of board size but also the size of the heat sink, and in some cases no heat sink is required.FmU嘉泰姆

   ±4% tolerance on output voltage within specified input voltages and output load conditions is guaranteed. Also, the oscillator frequency accuracy is within ±10%. External shutdown is included, featuring 70μA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions.FmU嘉泰姆
