General Description

The MCP1256, MCP1257, MCP1258 and MCP1259 are inductorless, positive regulated charge pump DC/DC converters.

The devices generate a regulated 3.3V output voltage from a 1.8V to 3.6V input.

The devices are specifically designed for applications operating from 2-cell alkaline, Ni-Cd, or Ni-MH batteries or by one primary lithium MnO2 (or similar) coin cell battery.
