说明

MAX17021/MAX17082/MAX17482为两相/单相、交错控制Quick-PWM™降压型VID电源控制器,用于笔记本电脑的CPU供电。真正的错相工作架构降低了对输入纹波电流的要求和输出电压纹波,同时简化了元件选择和电路板布局。Quick-PWM控制技术能够瞬时响应负载电流的快速阶跃变化。有源电压定位降低了功耗以及对大容量输出电容的要求,并可对钽电容、聚合物电容或陶瓷电容等大容量输出电容进行理想的电压定位补偿。

摆率控制器能够实现VID码之间的受控转换、受控的软启动和软关断以及受控地退出挂起状态。基于热敏电阻的温度传感器提供可编程的热故障报警输出(/VRHOT)。电流监测输出(IMON)提供与CPU功耗成比例的模拟输出电流(MAX17082/MAX17482)。当检测到任意输出欠压、过压(MAX17021/MAX17082)或热故障时,将关断控制器。电压调节器电源就绪(PWRGD)输出用于指示输出电压是否处于稳压范围。另外,MAX17021/MAX17082/MAX17482具有真差分电流检测和相位就绪(PHASEGD)输出,指示相位不平衡故障。

MAX17021满足IMVP-6+规范,MAX17082/MAX17482符合IMVP-6.5的要求。MAX17021/MAX17082/MAX17482采用5mm x 5mm、40引脚TQFN封装。
