Based on CSMC 0.13um 3.3V/1.2V Logic process, current design of the Battery Charger IP is a complete constant current/constant voltage linear charger for single cell lithium-ion and lithium-polymer ...

Sometimes I need a 3.3V power source but the only one that I have are the 1.2 volt rechargeable or the common 1.5V alkaline batteries therefore I’ve searched for some type of DC to DC boost converter ...

batteries to reach the voltage of a single-use alkaline battery at 1.5V or even maintain their 1.2V level for the operating life of the battery is an issue for some, particularly if you're powering ...

On the other hand, some P-channel devices work at lower voltages (approx 0.2V lower), and that suits it well for 1.2V battery applications. The rest is human–the mind visualizes well against ground ...
