MCP1258 - Low-Ripple Charge Pump

This page provides the datasheet information for the MCP1258, a member of the MCP1256 Low-Ripple Charge Pump family.

Datasheet Summary

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.

Features

  • Inductorless 1.5x, 2x Boost DC/DC Converter.
  • Output Voltage: 3.3V.
  • High Output Voltage Accuracy: - ±3.0% (VOUT Fixed).
  • Output Current Up To 100 mA.
  • 20 mVPP Output Voltage Ripple.
  • Thermal Shutdown and Short Circuit Protection.
  • Uses Small Ceramic Capacitors.
  • Switching Frequency: 650 kHz.
  • Low-Power SLEEP Mode: MCP1256/7.
  • BYPASS Mode: MCP1258/9.
  • Low-Power Shutdown Mode: 0.1 µA (Typical).
  • Shut.
