LM22679QTJ-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22679QTJ-ADJ/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator featuring an integrated 5A power switch. It operates with an input voltage range of 4.5V to 42V and provides an adjustable output voltage. The device utilizes a fixed switching frequency of 500kHz and is housed in a TO-263-7 (D2PAK) surface-mount package. It supports operation from -40°C to +125°C, meets AEC-Q100 automotive qualification standards, and includes built-in thermal shutdown and current limit protection.

• Includes comprehensive protection mechanisms such as thermal shutdown and current limiting

Voltage Regulators - DC DC Switching Regulators Applications

• Automotive electronics systems
• Industrial point-of-load regulation
• General-purpose DC/DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ADJ' confirms the adjustable output variant rather than a fixed voltage version. Confirm the 'NOPB' designation indicates lead-free and RoHS compliance status. Ensure the 'QTJ' prefix matches the required TO-263-7 package type and temperature grade specifications for your design requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck converter capable of handling up to 5A load current is required. It is suitable for applications needing an input voltage up to 42V. Consider the TO-263-7 package for its thermal performance advantages over smaller packages in high-power scenarios.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22679 series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM22678 but offers higher current capability. The family is designed for robust, cost-effective power management solutions in demanding environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM22679TJ-ADJ/NOPB or LM22679Q-ADJ/NOPB, provided the package and temperature grades align with system constraints.
