[原创] Maxim MAX77650(1)超低功耗PMIC解决方案

Maxim公司的MAX77650/MAX77651是用于低功耗可穿戴的高度集成电池充电和电源解决方案,两种器件具有单个电感多个输出(SIMO)降压/升压稳压器,150mA LDO以及高度可配置线性充电器,0.3μA待机电流,主要用在蓝牙耳机/智能耳戴式设备,健身,保健和运动监测,手持设备和物联网(IoT).本文介绍了MAX77650/MAX77651主要优势和特性,框图,应用电路,以及评估板MAX77650/MAX77651 EVK主要特性,框图,电路图,材料清单和PCB设计图.

The MAX77650/MAX77651 provides highly-integrated bat­tery charging and power supply solutions for low-power wearable applications where size and efficiency are critical. Both devices feature a SIMO buck-boost regulator that provides three independently programmable power rails from a single inductor to minimize total solution size. A 150mA LDO provides ripple rejection for audio and other noise-sensitive applications. A highly configu­rable linear charger supports a wide range of Li+ battery capacities and includes battery temperature monitoring for additional safety (JEITA).
