MCP1258-E/UN Description

Short technical summary and product information.

The MCP1258-E/UN from Microchip Technology is a positive regulated charge pump DC/DC converter designed for battery-powered applications. It generates a stable 3.3V output voltage from an input range of 1.8V to 3.6V, making it suitable for devices powered by 2-cell alkaline or Ni-MH batteries, or single lithium coin cells.

 

This device operates with a switching frequency of 650 kHz and offers high efficiency by automatically switching between 1.5x and 2x boost operations. It features a BYPASS mode for low-power applications, allowing system devices to remain biased with minimal current consumption. The output current capability is up to 100 mA with a low output voltage ripple of 20 mVPP.

 

Key features include thermal shutdown and short circuit protection, soft-start circuitry to minimize inrush current, and compatibility with 1.8V logic for its shutdown input. The MCP1258-E/UN is available in a compact 10-MSOP package, suitable for space-constrained designs. It operates across a wide temperature range of -40°C to +125°C.
