I have a circuit running at 3.3 volts
it is powered by a LM2576 with 5v output and this 5 volts will power a lithium charger chip and a 3.3 regulator(LP3962)
The problem is when the battery is charging or ful chargered the voltage can be from 3.0 to 4.2 volts... what regulator i need to put to in the place of the LP3962 in red after the charger chip ??
I think needs to be a regulator with input from 3.3 volts to 4.2 and output 3.3 volts.
Current peak is 3A because have a Motorola G24 modem.
Thanks
