Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, as the company merger affects part sourcing. Confirm the LLP-14 or VSON-14 package variant matches the schematic footprint. Ensure the suffix indicates the adjustable output version rather than fixed voltage options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck converter is required with up to 3 A load current. The adjustable output allows flexibility for various system voltages. Verify that the 260 kHz switching frequency aligns with thermal constraints and electromagnetic interference requirements for the target enclosure.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SIMPLE SWITCHER family, designed for high-efficiency DC-DC conversion. It integrates the switch, controller, and diode functions into a compact surface-mount package. The device simplifies design by reducing the number of external passive components needed compared to non-integrated solutions.
