IFX91041EJV Description

Short technical summary and product information.

The Infineon IFX91041EJV is a monolithic integrated circuit designed as a step-down (buck) switching voltage regulator. It is capable of driving loads up to 1.8A with excellent line and load regulation.

This series offers fixed output voltage versions of 5.0V and 3.3V, as well as an adjustable version. Key electrical specifications include an input voltage range of 4.75V to 45V and a switching frequency of 370kHz, which allows for the use of small passive components. The output voltage tolerance is typically ±2%, with a maximum of ±4% for the full load current range.

Designed for industrial applications, the IFX91041EJV features integrated protection functions such as current limitation and overtemperature shutdown. It also includes a soft-start function to limit inrush current and voltage overshoot during startup, and an enable function that reduces shutdown current consumption to less than 2uA.

The device is housed in a PG-DSO-8-27 package, suitable for surface mounting. Its operating temperature range is from -40°C to +125°C.
