Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM3673TL-ADJ/NOPB

LM3673TL-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3673TL-ADJ/NOPB is a synchronous step-down DC-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 2.7V to 5.5V and provides an adjustable output voltage from 1.1V to 3.3V. The device delivers a maximum output current of 350mA at a fixed switching frequency of 2MHz. It utilizes a 5-pin DSBGA package (1.41x1.08mm) and supports surface-mount installation. The component functions within a temperature range of -30°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates synchronous rectification for improved efficiency in compact designs
Features a high 2MHz switching frequency to minimize external passive component size
Supports adjustable output voltage configuration via external feedback resistors

Voltage Regulators - DC DC Switching Regulators Applications

Portable battery-powered electronic devices
Embedded systems requiring low-power regulation
Mobile communication equipment power stages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's latest documentation. Confirm the 'TLX' designation indicates reel packaging when sourcing. Ensure the design accounts for the 5-DSBGA thermal pad requirements for proper heat dissipation during operation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a small footprint due to the DSBGA-5 package. It is suitable for systems powered by single-cell lithium-ion batteries or similar 3V-5V sources. Consider the 350mA current limit when sizing for load requirements, and ensure the PCB layout supports the high-frequency switching characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3673 series of simple switcher regulators. It is distinct from the LM2673 series, which handles higher voltages and currents in larger packages. The LM3673 is designed specifically for low-voltage, space-constrained portable applications rather than industrial or high-power scenarios.
