目录 1.产品概述 2.产品特点 3.应用范围 4.技术规格书下载（PDF文档） 一.产品概述 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. 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. ±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. 二.产品特点 ‹ Guaranteed 3A output current ‹ 3.3V, 5V, and adjustable versions ‹ Wide input voltage range, up to 37V ‹ Internal oscillator of 155KHz around fixed frequency ‹ Wide adjustable version output voltage range, from 1.24V to 37V±4% max over line and load conditions ‹ Low standby current, typ. 70μA, at shutdown mode ‹ Requires only 4 external components ‹ Thermal shutdown and current limit protection ‹ P+ product enhancement tested 三.应用范围 ‹ LCD Monitors ‹ ADD-ON Cards Switching Regulators ‹ High Efficiency Step-Down Regulators ‹ Car Electronic 四.技术规格书（产品PDF) 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 五.产品封装图 六.电路原理图 七.相关芯片选择指南 更多同类产品......
