Chinese introduction
The MCP1258 family of devices is a non-inductive, positive voltage regulated charge pump DC/DC converter. It converts input voltages from 1.8V to 3.6V into a stable 3.3V output voltage. Designed for applications powered by two alkaline, nickel-cadmium (NiCd), nickel-metal hydride (Ni-MH) batteries or powered by a single lithium-manganese (Li-MnO2) or similar disposable button cell of.

Typical application circuit diagram of MCP1258:
