LM3673TL-1.2/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3673TL-1.2/NOPB is a synchronous step-down DC-DC converter manufactured by Texas Instruments, featuring a fixed 1.2 V output and a 350 mA maximum output current. It operates with a switching frequency of 2 MHz and supports an input voltage range from 2.7 V to 5.5 V. The device utilizes a DSBGA-5 package and functions within a temperature range of -30°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous buck topology for high efficiency
• Fixed 1.2 V output voltage configuration
• Compact DSBGA-5 surface-mount packaging

Voltage Regulators - DC DC Switching Regulators Applications

• Portable battery-powered electronics
• Embedded systems power regulation
• Low-voltage digital circuit supply

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TL' against the official datasheet to confirm the fixed 1.2 V output variant. Ensure the DSBGA-5 package dimensions match the PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2 V rail is required with moderate current demands up to 350 mA. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance in the small DSBGA-5 package for dense layouts.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3673 series of synchronous step-down converters. It shares architectural similarities with other members like the adjustable LM3673TL-ADJ/NOPB but provides a fixed output voltage to simplify design implementation. The series targets applications requiring efficient power management in space-constrained environments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM3673TL-ADJ/NOPB serves as a functional substitute if an adjustable output voltage is acceptable instead of the fixed 1.2 V setting. Both devices share the same package, switching frequency, and general electrical characteristics within the LM3673 family.
