LM22675MR-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22675MR-ADJ/NOPB is a step-down switching voltage regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It integrates a 1A power switch and operates with an input voltage range of 4.5V to 42V. The device features a fixed internal switching frequency of 500kHz, enabling the use of small external components. It provides an adjustable output voltage starting from 1.285V. The component supports a junction temperature range from -40°C to +125°C and is housed in an 8-SO-PowerPad package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MR' corresponds to the SO-PowerPAD-8 tape-and-reel packaging configuration required for your assembly process. Confirm that the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the manufacturer part number against the latest datasheet revision to ensure functional equivalence with existing design specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck converter is needed with up to 1A load capacity. It is suitable for designs requiring wide input voltage tolerance up to 42V. The adjustable output feature allows flexibility for various target voltages above 1.285V. Consider the thermal performance of the PowerPAD package for heat dissipation requirements in compact layouts.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the LM22675 series, which shares architectural similarities with the LM2675 but offers higher integration and switching frequency. Unlike the LM22674, it supports higher output current. The device simplifies design through integrated compensation and protection features, reducing the external component count compared to discrete solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22675MRE-5.0/NOPB serves as a direct alternative if a fixed 5V output is acceptable instead of an adjustable one. Other members of the LM2267x family may offer different current ratings or pinouts; verify electrical parameters and package dimensions before substitution.
