Embedded systems requiring compact power management

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the specific suffix /NOPB indicates lead-free packaging compliant with RoHS standards. Ensure the ordering part number matches the fixed 1.2V output variant to avoid confusion with adjustable or other fixed voltage versions within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when space constraints are critical due to its small footprint. It is appropriate for designs requiring a stable 1.2V rail from single-cell lithium-ion sources. Consider the 4MHz switching frequency for smaller external passive components. Verify that the load current does not exceed the 1A limit and that the input voltage remains within the specified 2.3V to 5.5V window.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM3691 series of high-accuracy, miniature step-down converters. It shares architectural similarities with variants like the LM3691TLX-1.8/NOPB and LM3691TLX-3.3/NOPB, differing primarily in the fixed output voltage setting. The series is designed for applications where size and efficiency are prioritized over programmability.
