Product introduction

TPS51222 固定频率 99% 占空比峰值电流模式笔记本系统功率控制器

illustrate

该TPS51222是一款双通道同步降压稳压器与两个LDO控制器。 This technology optimizes the 5-V/3.3-V system controller, cost-effectively powering 2- to 4-cell notebook computers. TPS51222支持的高效率，快速瞬态响应，99％工作周期操作。它支持从1 V电源输入电压范围从4.5 V至32 V和输出电压为12五，峰值电流模式支持稳定运行与ESR电容和输出精度较低。高占空比（99％）的运作和广泛的输入/输出电压范围支持灵活的小型移动电脑设计和其他各种应用。固定频率可以在200千赫到1兆赫的电阻，每个通道运行180 °异相。
