Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '1H' confirms the fixed 3.3 V output variant, as other suffixes may indicate adjustable or different fixed voltages. Ensure the order quantity matches the reel packaging specifications provided by the distributor. Confirm RoHS compliance status if required for specific regional regulations. Check for any recent PCN notifications regarding marking or assembly site changes that might affect part identification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a stable 3.3 V rail is required for automotive loads within the 2.7 V to 6 V input window. The 2 A current capability suits moderate power applications without requiring external heat sinking in typical layouts. The wide frequency range allows optimization for EMI performance or component size. Compare against adjustable variants if system design requires non-standard voltage levels.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS62850x-Q1 family of automotive-grade DC-DC converters. It shares core architecture with adjustable versions like the TPS628502QDRLRQ1 but provides a fixed output to simplify design. The family targets compact power solutions for modern vehicle electronic control units requiring high reliability and small footprint.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other TPS62850x-Q1 variants with matching output voltage and current ratings. Verify pin compatibility and thermal characteristics before swapping. Adjustable versions require external resistor networks, while fixed voltage alternatives offer immediate drop-in replacement if electrical parameters align.
