Hi everyone,
I'm trying to select a battery charger to my portable application. I'm going to use Lithium-Ion/Polymer battery and the maximum current output to the system is going to be 2.0A, but I need that this charger has an output to the system from 3.3V to 4.5V regardless of the battery voltage, i.e. when the battery voltage is from 3.0V to 3.3V the IC has to step up the voltage at least to 3.3V.
Does anyone know whether there is any battery charger IC with this requirements?
Best regards
