  • Product introduction

在高速，低功耗集成电路UCC3807系列包含了所有的离线和开关用最少的外部组件数电源供应器直流到直流固定频率电流模式所需的控制及驱动电路。

这些设备是类似于UCC3800家庭，但随着用户可编程最大占空比附加功能。 The oscillator frequency and maximum duty cycle are programmed with two resistors and one capacitor. 该UCC3807系列还具有内部软启动和完整的周期内前缘消隐的电流检测输入。

在UCC3807系列提供了封装，温度范围选项，以及各种临界电压等级的选择。 这家有欠压锁定阈值和离线和电池供电系统滞后的水平。
