I have made a custom pcb of STEVAL-ISV019V1 circuit. In that ,we need to charge 3.7v lithium ion battery via USB supply and solar panel. When I connect USB supply or panel voltage as input voltage the complete input voltage is coming in the bat...
In buck-boost configuration SPV1050 have only 30mA output current. Is there any other MPPT IC available which is having large output current and input voltage of 3.4V to 12V?
I have checked the resistor values of EOC and VEOC as mentioned in the datasheet. but still When I connect USB supply or panel voltage as input voltage the complete input voltage is coming in the battery charging point. where as the lithium battery ...
when we connect battery alone, the LDO1 and LDO2 outputs are not getting. but incase of solar panel and USB power supply store pin is shorted and the LDO outputs are working .Our device is working on battery supply we use USB only for battery chargi...
