I have a li-ion battery charged with a charge chip, but when it is fully charged or charging the output to the system is 4.2Volts, and when is discharging the voltage go down (near 3 volts).
So i need a Buck-Boost Regulator form my GSM application, my modem is a motorola G24( 3.3 volts) and have a current peak when transmitting.
what is the Buck-Boost Regulator i need to use to extract power when battery is under 3.3 volts ?
I found a some regulators, but most regulators i found cannot be found on digikey or mouser (some of then is out of production).
Thanks for suggestions
