Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging options. Confirm the TSSOP-16 package availability matches your assembly requirements. Check for any recent obsolescence notices as some variants may be discontinued. Ensure the fixed 3.3 V output aligns with your design needs rather than using the adjustable version.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V rail is required with up to 2.5 A load capability. It is suitable for designs prioritizing efficiency over adjustable output flexibility. Compare against the LM2655-ADJ variant if variable output voltages are needed. Consider the 330 kHz switching frequency for inductor size trade-offs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2655 family of high-efficiency synchronous buck regulators. It shares architectural similarities with other TI current-mode controllers but offers integrated power switches. The series targets applications demanding compact solutions with high power density and wide input voltage ranges.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2655MTCX-ADJ/NOPB for adjustable output or LM2655MTCX-5.0/NOPB for different fixed voltages. Verify pin compatibility and thermal performance before substitution.
