IFX91041EJVXUMA1

Voltage Regulators - DC DC Switching Regulators Overview

The IFX91041EJVXUMA1 is a monolithic synchronous step-down switching regulator from Infineon Technologies, designed for high-efficiency power conversion. It integrates a 45 V input range buck topology with an adjustable output voltage capability spanning from 600 mV to 16 V. The device delivers a continuous output current of 1.8 A and operates at a fixed switching frequency of 370 kHz. It functions within an extended temperature range of -40 °C to +125 °C and is housed in a compact SOIC-8 surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a synchronous buck converter with internal high-side and low-side MOSFETs for efficient step-down regulation.
• Features a fixed 370 kHz switching frequency to optimize external component size and transient response.
• Includes comprehensive protection mechanisms such as overcurrent protection, thermal shutdown, and undervoltage lockout.

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial point-of-load (POL) regulation
• Telecommunications infrastructure power distribution
• Consumer electronics DC-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix XUMA1 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Infineon documentation prior to integration. Ensure EOL or obsolescence status is checked, as availability may be restricted. Validate that the SOIC-8 footprint matches your PCB design constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a single-output 1.8 A solution with a wide input voltage range up to 45 V. It is suitable where space is limited due to the SOIC-8 package. Consider alternatives if higher current capacity or multiple outputs are required. Verify that the 370 kHz frequency aligns with your noise and efficiency requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the IFX91041 series of switching regulators. It serves as a non-adjustable or fixed-output variant depending on the specific suffix configuration, distinct from the adjustable IFX91041EJV. The series targets general-purpose power management needs in industrial and consumer sectors.
