LM22672MR-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22672MR-5.0/NOPB is a step-down switching regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 42 V and provides a fixed 5 V output at up to 1 A. The device integrates a 1.1 A power switch and features a 500 kHz switching frequency. It includes adjustable soft-start, current limit, thermal shutdown, and enable functions. Packaged in an 8-SO PowerPAD (Exposed Pad) for surface mount installation, it supports operation from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 1.1 A power switch for compact design
• Includes adjustable soft-start and cycle-by-cycle current limiting
• Features thermal shutdown and enable control

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Industrial control power supplies
• Telecommunications equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact part number against official Texas Instruments documentation to confirm the fixed 5.0 V output variant. Ensure the suffix matches the required packaging format, as the MR package typically ships in tubes while the MRX variant uses reels. Cross-reference RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required within the SIMPLE SWITCHER series. Compare against the LM22672MR-ADJ/NOPB if variable output is needed, or the LM22671MR-5.0/NOPB for lower current applications. Consider the LM22673 series if higher output current capacity is necessary for the specific load requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2267x SIMPLE SWITCHER family of buck converters. It shares architectural similarities with the LM22671 and LM22673 models but is distinguished by its 1 A output capability and fixed 5.0 V configuration. The family is characterized by high efficiency and integrated protection features suitable for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22672MR-5.0/NOPB is functionally equivalent to LM22672MR-5.0 without the NOPB suffix regarding electrical performance. Verify pinout compatibility with other 8-SO PowerPAD regulators if considering alternative manufacturers.
