UCC2805-Q1 汽车类低功耗 BiCMOS 电流模式 PWM

描述

UCC2800 /1/2/3/4/5系列高速，低功耗集成电路包含所需的所有控制和驱动器组件用于离线和DC-DC固定频率电流模式开关电源，零件数量最少。

这些器件具有与UC2842 /3/4/5系列相同的引脚配置，并且提供内部全周期软启动和电流检测输入的内部前沿消隐的附加功能。

UCC2800 /1/2/3/4/5系列提供最大占空比选择和临界电压水平。较低的参考部件（如UCC2803和UCC2805）最适合电池供电系统，而UCC2802和UCC2804的较高参考电压和较高的UVLO迟滞使其成为离线电源的理想选择。

UCC280xQDRQ1系列的工作温度范围为40°C至125°C，符合AEC-Q100集成电路压力测试资格。
