MP1497DJ-LF-Z Description

Short technical summary and product information.

The MP1497DJ-LF-Z is a high-efficiency, synchronous, step-down buck regulator from Monolithic Power Systems. It operates from a 4.5V input voltage and delivers up to 3A of continuous output current. The switching frequency is fixed at 500kHz, enabling a compact solution with small external components.

 

The device features an adjustable output voltage and a positive output configuration. It includes a synchronous rectifier for improved efficiency, reducing the need for an external Schottky diode. The operating temperature range spans -40°C to 125°C, suitable for industrial and automotive environments.

 

The MP1497DJ-LF-Z is housed in a surface-mount TSOT23-8 package (also available as SOT-23-8 Thin). This package is ideal for space-constrained applications requiring a high-density power solution.
