Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DLCR' against the manufacturer's official datasheet to confirm the reel packaging configuration and tape-and-reel specifications. Ensure that the ordering documentation explicitly references the TPS62823 family parameters, as variations in suffixes may indicate different thermal or handling characteristics. Cross-reference the component marking with the official identification guide to prevent counterfeit risks during acquisition.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3 A output current capability is required within a small form factor. The 2.2 MHz switching frequency enables the use of smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the 2.4 V minimum input voltage constraint to ensure compatibility with battery discharge profiles. The adjustable output feature simplifies design adaptation for different logic voltage levels without changing the base IC.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6282x series of synchronous step-down converters, which are optimized for space-constrained portable applications. The series shares common architectural features such as high efficiency and compact packaging. The TPS62823 variant specifically distinguishes itself by offering a higher 3 A output current capacity compared to lower-current siblings in the same family, making it suitable for more demanding processing loads.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other members of the TPS6282x family, such as the TPS62821 or TPS62822, if lower output current ratings are acceptable. For equivalent performance, verify that alternative parts support the same 3 A current rating and 2.2 MHz switching frequency. Ensure that any replacement maintains compatibility with the 8-VSON-HR package dimensions to preserve PCB layout integrity.
