CXDC6575

CXDC6575由带PWM控制的降压开关调节器组成。这些器件包括参考电压源、振荡电路、误差放大器、内部PMOS等。
CXDC6575/A具有低纹波功率、高效率和良好的瞬态特性。该PWM控制电路能够使占空比从0线性上升到100%。该转换器还包含一个误差放大电路和一个软启动电路,以防止启动时的s超调。内置使能功能、过流保护功能和短路保护功能,当OCP或SCP发生时,工作频率由400KHz降至60KHz。此外,内置内部补偿块以使外部组件计数最小。
这些集成电路可以作为降压开关稳压器。当与SOP-8L微型封装相结合时,它们是便携式设备的理想电源单元,具有低电流消耗等突出特点。由于这种转换器可以容纳高达18伏的输入电压,所以在通过交流适配器工作时也是理想的选择。

一.产品概述Eq9嘉泰姆


     CXDC6575 consists of step-down switching regulator with PWM control. These devices include a reference voltage source, oscillation circuit, error amplifier, internal PMOS and etc.Eq9嘉泰姆

     CXDC6575/A provides low-ripple power, high efficiency and excellent transient characteristics. The PWM control circuit is able to very the duty ratio linearly from 0 up to 100%. This converter also contains an error amplifier circuit as well as a soft-start circuit that prevent s overshoot at startup. An enable function, an over current protect function and a short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced from 400KHz to 60KHz. Also, an internal compensation block is built in to minimum external component count. Eq9嘉泰姆

    These ICs can function as step-down switching regulators. They serve as ideal power supply units for portable devices when coupled with the SOP-8L mini-package, providing such outstanding features as low current consumption. Since this converter can accommodate an input voltage of up to 18V, it is also ideal when operating via an AC adapter.Eq9嘉泰姆
