Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'TLX' indicates tape and reel packaging configuration. Confirm AEC-Q100 qualification status if automotive grade compliance is required. Ensure the NOPB designation confirms lead-free and RoHS compliance. Cross-reference the manufacturer part number with official TI documentation to validate pinout and thermal characteristics before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed standard 15V limits but remain below 33V continuous. The 1.25A output current suits moderate power applications requiring compact footprints. Consider the 2MHz frequency for smaller passive components compared to lower-frequency alternatives. Evaluate thermal performance in the WFBGA package against system heat dissipation capabilities.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3491x family of ultra-small buck converters. It shares architectural similarities with the LM34919CQTLX/NOPB but offers higher current capacity (1.25A vs 600mA) and different input voltage ranges. The family targets space-constrained designs requiring robust transient response and wide input voltage tolerance.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM34917 variants such as LM34917ATL/NOPB. Verify package compatibility and electrical specifications match requirements. Alternative families may require redesign of feedback networks due to different reference voltages or control topologies.
