Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer designation, as the LM2694MT originates from National Semiconductor prior to its acquisition by Texas Instruments. Ensure the component matches the required TSSOP-14 package and lead configuration. Confirm RoHS compliance status and check for any specific handling requirements associated with legacy part numbers during integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for converting higher bus voltages down to lower logic or analog rails. The 1 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance of the TSSOP-14 package relative to the expected load current and ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2694 series of synchronous buck regulators. It serves as a bridge between legacy National Semiconductor products and the current Texas Instruments portfolio. The MT suffix specifically denotes the TSSOP-14 plastic small outline package, distinguishing it from other form factors like the SD variant.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2694SD/NOPB is a verified substitute offering identical electrical specifications but utilizes a WSON-10 package instead of TSSOP-14. Designers must verify footprint compatibility and thermal dissipation characteristics when transitioning between these package types.
