[原创] Maxim MAX77650小型锂电池高集成度充电和电源解决方案

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,具有SIMO降压-升压稳压器,有三个输出,可编电压稳压从3.6-4.6V,可编端电流0.375-45mA,主要用在蓝牙耳机,健身和活动监视器,可提设备和物联网(IoT).本文介绍了MAX7765优势和主要特性,功能框图和应用电路,以及MAX77650/MAX77651评估板EVK主要特性,元件分布图,电路图,材料清单和PCB设计图.

The MAX77650/MAX77651 provide 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).
