MP2451DJ-LF-Z Description

Short technical summary and product information.

The MP2451DJ-LF-Z is a step-down (buck) switching regulator from Monolithic Power Systems. It provides a positive adjustable output voltage with a maximum output current of 600mA. The device operates at a fixed switching frequency of 2MHz, allowing for small external components and a compact design. It features a single output and does not include synchronous rectification. The regulator is designed for a wide operating temperature range from -40°C to 125°C (TJ). It is housed in a surface-mount SOT-23-6 Thin, TSOT-23-6 package, with a supplier device package of TSOT-23-6. This regulator is suitable for applications requiring efficient voltage conversion from a higher input voltage to a lower adjustable output. Its small footprint and high switching frequency make it ideal for space-constrained and power-sensitive designs.
