[原创] ADI ADP5301超低功耗降压调节器解决方案

ADI公司的ADP5301是超低功耗降压调节器,具有业界最高的超轻负载电源转换效率，可延长便携式设备的电池寿命,额定效率为90%,静态电流仅为180 nA,工作电压2.15V to 6.50V,非常适合物联网(IoT)应用,包括无线传感器网络和可穿戴设备如健身手环和智能手表.本文介绍了ADP5301主要特性,框图,应用电路图,以及评估板ADP5301-EVALZ主要特性,电路图,材料清单和PCB设计文件图.

The ADP5301 is high efficiency, ultralow quiescent current step-down regulator that draws only 180 nA quiescent current to regulate the output at no load. The ADP5301 runs from an input startup voltage range of 2.15 V to 6.50 V, allowing the use of multiple alkaline or NiMH, Li-Ion cells, or other power sources. The output voltage is selectable from 0.8 V to 5.0 V by an external VID resistor and factory fuse. The total solution requires only four tiny external components. The ADP5301 can operate between hysteresis mode and PWM mode via the SYNC/MODE pin.
