Hi
I would like to use one battery which has a V=3.7V. However my circuit (sensor and uC) requires 5V to operate (stable 5V).
Can someone please tell me how to do this?
One option is to double the voltage of the battery to 7.4V using a Dc-Dc converter (e.g.MAX1683). Then to use a Voltage regulator to ensure that I have a STABLE 5V. (I notice that the Dc-Dc converters V is not stable and decreases with Vin- is this right)?
Can someone please comment on this approach?
Are there better solutions?
Thank you in advance for your help.
