ling1995 Posted March 18, 2017 Report Share Posted March 18, 2017 Hello~all,it's my first time to be here.I hope I chose the right forum to ask for help for my project ! In my project,I need to use boost circuit and I rose the battery from 3.7V to 5V. After that,The chip--XC6371 (this one) was surely chosen.According to it’s datasheet, I design a boost circuit.Unfortunately, I can’t get a right voltage of output whatever I did. The outputted voltage is lower than the inputted voltage.Anybody who have used it can help me? I have upload the schematic diagram,please have a look. In my circuit,the capacitor of 47uf has used in the outputted port while the another one with 220uf in the inputted port. Others I used is 100uf. Anybody can help me? Any suggestions ? Thanks a lot ! PS: This is the circuit,please have a look! Quote Link to comment Share on other sites More sharing options...
audioguru Posted March 19, 2017 Report Share Posted March 19, 2017 The datasheet shows how the output voltage is marked. It could be from 2V to 7V in 0.1V increments. I think yours is 2.3V. Quote Link to comment Share on other sites More sharing options...
IbEliteTutor Posted April 4, 2017 Report Share Posted April 4, 2017 According to my view Circuit seems to be fine but will be better if you have a look at output voltage Quote Link to comment Share on other sites More sharing options...
