MCP1252 - Low Noise / Positive-Regulated Charge Pump

Description

The MCP1252/3 are inductorless, positive-regulated charge pump DC/DC converters.

The devices generate a regulated fixed (3.3V or 5.0V) or adjustable output voltage.

Features

  • Inductorless, Buck/Boost, DC/DC Converter.
  • Low Power: 80 µA (Typical).
  • High Output Voltage Accuracy: - ±2.5% (VOUT Fixed).
  • 120 mA Output Current.
  • Wide Operating Temperature Range: - Industrial Temperature (I): -40°C to +85°C - Extended Temperature (E): -40°C to +125°C.
  • Thermal Shutdown and Short-Circuit Protection.
  • Uses Small Ceramic Capacitors.
  • Switching Frequency: - MCP1252: 650 kHz - MCP1253: 1 MHz.
  • Low-Power S.
