Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM3671TL-1.2/NOPB

LM3671TL-1.2/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3671TL-1.2/NOPB is a fixed-output step-down DC-DC converter manufactured by Texas Instruments, featuring a 1.2V output and 600mA maximum load current capability. It operates with an input voltage range of 2.7V to 5.5V and utilizes a 2MHz switching frequency. The device employs synchronous rectification for high efficiency and integrates automatic transition between PWM and PFM modes to optimize performance across varying load conditions.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Intelligent mode switching between low-noise PWM and low-current PFM operation
High-efficiency internal synchronous rectification
Compact design requiring only three external surface-mount components

Voltage Regulators - DC DC Switching Regulators Applications

Portable mobile devices
Battery-powered systems
Low-voltage circuit power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TL' indicates the DSBGA-5 package variant distinct from MF or QMF series. Confirm RoHS compliance via NOPB designation. Ensure application circuits match the fixed 1.2V output requirement as adjustable versions differ in pinout configuration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2V rail is required within a 2.7V to 5.5V input window. The 2MHz frequency enables smaller passive components compared to lower-frequency alternatives. Verify thermal requirements for the DSBGA-5 package under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM3671 family optimized for portable electronics. The TL suffix denotes the specific DSBGA-5 package type, distinguishing it from SOT-23-5 (MF) or automotive-grade (QMF) variants within the same functional architecture.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3671MF-1.2/NOPB offers identical electrical specifications but utilizes an SOT-23-5 package instead of DSBGA-5. Cross-reference footprint dimensions before substitution.
