The MCP1252/3 are inductorless, positive-regulated charge pump DC/DC converters designed for low noise and high efficiency. They generate a regulated fixed (3.3V or 5.0V) or adjustable output voltage and can deliver up to 120mA output current. The devices automatically switch between buck/boost operation, allowing the input voltage to be lower or higher than the output voltage. Applications include white LED backlighting, color display bias, and flash memory supply voltage.
