LM22673TJ-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22673TJ-ADJ/NOPB is a 3A step-down voltage regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with an input voltage range of 4.5V to 40V and provides an adjustable output voltage. The device features a fixed switching frequency of 500kHz and includes adjustable soft-start and current limit functions. It is housed in a 7-pin TO-263 (D2PAK) package and supports an operating junction temperature range from -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a 3A power switch for high-current step-down conversion
Includes adjustable soft-start and cycle-by-cycle current limit protection
Utilizes a fixed 500kHz switching frequency to minimize external component size

Voltage Regulators - DC DC Switching Regulators Applications

Industrial point-of-load regulation
Embedded system power supplies
Communication equipment backend power

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the ordering suffix matches 'NOPB' to ensure lead-free compliance and specific package variant accuracy. Confirm the manufacturer designation as Texas Instruments, as the National Semiconductor brand was acquired. Cross-reference the full part number against official TI databases to distinguish between the standard LM22673 and the adjusted output version.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck converter with 3A continuous current capability is required. The TO-263 package offers superior thermal dissipation compared to smaller surface-mount options. Ensure the application requires an adjustable output voltage rather than a fixed rail. The 500kHz frequency balances efficiency and passive component size.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2673/LM22673/LM32673 SIMPLE SWITCHER family. The 'LM22673' designation indicates automotive-grade qualification (-40°C to 125°C), while 'TJ' specifies the TO-263-7 package. The 'ADJ' suffix denotes the adjustable output voltage configuration, allowing flexibility in target voltage selection via external feedback resistors.
