Microchip MCP1252/3 Low Noise Positive-Regulated Charge Pump Datasheet
The MCP1252 and MCP1253 are inductorless, positive-regulated charge pump DC/DC converters designed for applications requiring low noise and high efficiency. They generate a regulated fixed (3.3V or 5.0V) or adjustable output voltage and can deliver up to 120 mA of output current. The devices automatically switch between buck and boost operation depending on whether the input voltage is lower or higher than the output voltage.
