LM22673TJE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22673TJE-5.0/NOPB is a Texas Instruments switching voltage regulator featuring the SIMPLE SWITCHER architecture. It operates as a step-down converter with a fixed 5.0 V output and a maximum output current of 3 A. The device accepts an input voltage range from 4.5 V to 42 V. It utilizes a 500 kHz switching frequency and is housed in a TO-263 (DPAK) surface-mount package with seven pins. The component supports an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number suffix matches the required output voltage configuration, as the SIMPLE SWITCHER family offers both fixed and adjustable variants. Confirm the package type corresponds to the thermal management requirements of the target application. Ensure compliance with RoHS standards if mandated by the end-product specifications. Cross-reference the datasheet for accurate footprint dimensions during PCB layout design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from higher input voltages up to 42 V. The 3 A current rating suits moderate power applications where space constraints favor the TO-263 package over larger through-hole options. Consider the 500 kHz frequency for balancing component size and efficiency. Evaluate thermal dissipation capabilities based on the expected load current and ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2267x series of monolithic integrated step-down converters. The series provides a complete solution for buck conversion, integrating the switch, control logic, and protection circuits. The LM22673 variant specifically targets 3 A applications, distinguishing it from lower or higher current counterparts within the same product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22673TJE-ADJ/NOPB serves as a functional substitute if an adjustable output voltage is acceptable instead of the fixed 5.0 V setting.
