Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM22670QTJ-5.0/NOPB

LM22670QTJ-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22670QTJ-5.0/NOPB is a SIMPLE SWITCHER step-down voltage regulator manufactured by Texas Instruments. It integrates a 3A current switch and operates from an input voltage range of 4.5V to 42V. The device provides a fixed 5V output with a switching frequency of 500kHz. It features frequency synchronization capability, adjustable soft-start, and thermal shutdown protection. Qualified under AEC-Q100 standards for automotive applications, it is housed in a TO-263-7 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a high-efficiency 3A power switch for compact point-of-load regulation
Supports external clock synchronization to reduce system-wide electromagnetic interference
Includes programmable soft-start to limit inrush current during startup
Features comprehensive protection mechanisms including thermal shutdown and current limiting

Voltage Regulators - DC DC Switching Regulators Applications

Automotive electronics requiring AEC-Q100 qualified components
Industrial distributed power architectures
Point-of-load (PoL) conversion modules
Battery-powered equipment with wide input voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QTJ' against the manufacturer's official datasheet to confirm the exact package variant and temperature grade. Ensure the ordering part number matches the required tape-and-reel quantity specifications. Confirm RoHS compliance status via the latest product data sheet before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required with up to 3A load capacity. It is suitable for designs needing synchronization to an external clock source to manage noise. Consider the TO-263-7 package for adequate thermal dissipation in space-constrained PCB layouts without active cooling solutions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22670 family of SIMPLE SWITCHER regulators. It shares core architecture with other variants differing primarily in output voltage settings and package types. The series is designed for high-efficiency DC/DC conversion in automotive and industrial environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22670QTJ-ADJ/NOPB offers adjustable output voltage instead of fixed 5V. LM22679QTJ-5.0/NOPB provides higher 5A output current capability. LM22670MR-5.0/NOPB utilizes an SOIC-8 PowerPAD package.
