The MCP1257-E/MF from Microchip Technology is a positive regulated charge pump DC/DC converter designed for battery-powered applications. It generates a stable 3.3V output from an input voltage ranging from 1.8V to 3.6V, making it suitable for devices powered by 2-cell alkaline or Ni-MH batteries, or a single lithium coin cell.
This device features an inductorless design, utilizing small ceramic capacitors for a compact solution. It operates with a high output voltage accuracy of ±3.0% and can deliver up to 100 mA of output current with a low output voltage ripple of 20 mVPP. The switching frequency is fixed at 650 kHz, which helps avoid interference with sensitive IF bands.
Key features include thermal shutdown and short circuit protection for enhanced reliability. The MCP1257-E/MF is available in a 10-pin DFN (3x3 mm) package, suitable for surface mounting. It operates across a wide temperature range of -40°C to +125°C.
