Maxim公司的MAX17651是超低静态流高压线性稳压器,非常适用用在工业和电池供电的系统.器件的输入电压从4V到60V,提供高达100mA负载电流,无负载时的静态电流仅为8μA.输出电压从0.6V到58V电压范围内可调.反馈电压对温度的精度为±2%. 开漏低电平的PGOOD引脚提供功率良好信号给系统,以得到输出电压的成功地控制.器件还集成使能引脚(EN),允许用户把部件接通或关闭.器件具有热关闭特性,关断芯片温度超过165°C的部分. MAX17651工作在工业温度-40°C 到 +125°C,采用6引脚紧凑TSOT和6引脚(3nnx3mm)TDFN封装.主要用在低电流工业电源,电池供电的设备,开关电源的后稳压器,公用计量和遥控传感器.本文介绍了MAX17651主要优势和特性,功能框图, 5V输出应用电路图以及评估板MAX17651EVKITA#主要特性,电路图,材料清单和PCB设计图.

 

The MAX17651 ultra-low quiescent current, high-voltage linear regulator is ideal for use in industrial and battery-operated systems. The device operates from a 4V to 60V input voltage, delivers up to 100mA of load current, and consumes only 8μA of quiescent current at no load. The device consumes only 0.9μA current when in shutdown. Output voltage is adjustable in the 0.6V to 58V voltage range. Feedback voltage accuracy is ±2% over temperature.

An open-drain, active-low PGOOD pin provides a power-good signal to the system upon achieving successful regulation of the output voltage. The device also incorporates an enable pin (EN) that allows the user to turn the part on or off. The device has a thermal shutdown feature that shuts down the part when the die..
