Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered portable devices requiring efficient DC-DC conversion
• Industrial control systems operating within wide temperature ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the required 16-TSSOP footprint. Check datasheet revisions for any updates to electrical characteristics or recommended pin connections before finalizing design integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for converting 4V–14V inputs to lower adjustable voltages at currents up to 2.5A. The synchronous design offers higher efficiency compared to non-synchronous alternatives. Consider the 330 kHz frequency for balancing component size and noise. Ensure the application requires a single output channel and fits within the specified thermal envelope.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM265x family of high-efficiency synchronous switching regulators. It shares architectural similarities with the LM2650 and LM2651 but differs in output current capacity and package options. The LM2655 specifically targets applications requiring 2.5A output in a smaller form factor than the SOIC-24 packaged variants.
