[原创] Cypress MB39C831太阳能和热能能量收获电源管理方案

Cypress公司的MB39C831是超低电压升压太阳能和热能能量收获电源管理集成电路,包括根据太阳能最大功率跟踪(MPPT)来控制DC/DC转换器输出和对锂电池安全充电保护功能,输入电压0.3V-4.75V,输出电压3.0V-5.0V,最低起动电压0.35V,主要用在太阳能收获,锂电池太阳能充电器,手持音频播放器,手机,电子书,电子词典,无线遥控器和传感器节点.本文介绍了MB39C831主要特性,框图和应用电路,以及评估板MB39C831-EVB-03主要指标,框图,应用连接图,以及电路图,材料清单和PCB设计图.

The MB39C831 is the high-efficiency synchronous rectification boost DC/DC converter IC which efficiently supplies energy gettingfrom the solar cell with the single cell or multiple cells, or from the thermoelectric generator (TEG) to the Li-ion battery.

It contains the function to control the DC/DC converter output following the maximum power point of the solar cell (MPPT:

Maximum Power Point Tracking) and the protection function to charge the Li-ion battery safely.

It is possible to start-up from 0.35 V using the low-voltage process and adapts the applications which the single cell solar cell istreated as the input.

MB39C831主要特性:

 Operation input voltage range : 0.3 V to 4.75 V
 Output voltage adjustment range : 3.0 V to 5.0 V
 Minimum input voltage at start-up : 0.35 V
 Quiescent Current (No load) : 41 μA..
