LM22670TJE-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22670TJE-ADJ/NOPB is a SIMPLE SWITCHER® step-down voltage regulator manufactured by Texas Instruments. It integrates a 3A switch and operates from an input voltage range of 4.5V to 42V, delivering an adjustable output voltage starting at 1.258V. The device features a fixed switching frequency of 500kHz, enabling the use of small external components. It supports buck and inverting topologies within a TO-263 (D2PAK) package. Key electrical parameters include a quiescent current of 3.4mA and operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm pinout and functional compatibility. Ensure the TO-263 package variant matches the required thermal dissipation needs. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3A continuous output current is required with a wide input voltage range up to 42V. The 500kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the TO-263 package for its balance of thermal performance and board space efficiency in medium-power applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2267x family of SIMPLE SWITCHER regulators, which are designed for ease of use and high efficiency. The family includes variants with different current ratings and packages, such as the LM22676 and LM22679. The LM22670 specifically targets applications requiring 3A output capability in a robust surface-mount package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22670TJE-ADJ/NOPB is functionally equivalent to LM22670TJE-ADJ. Cross-reference with LM22676 or LM22679 if higher current capacity is needed, noting differences in package and thermal characteristics.
