The Microchip Technology MCP1257-E/UN 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 range of 1.8V to 3.6V, making it suitable for devices powered by 2-cell alkaline or Ni-MH batteries, or single-cell lithium batteries.
This device features high efficiency by automatically switching between 1.5x and 2x boost operations. It offers an output current of up to 100 mA 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. The MCP1257-E/UN includes thermal shutdown and short circuit protection for enhanced reliability.
Designed for space-constrained applications, it utilizes small ceramic capacitors and is available in a compact 10-MSOP package. The surface mountable design simplifies integration into printed circuit boards. The operating temperature range is -40°C to +125°C, ensuring performance in various environmental conditions.
