Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging quantity and lead time specifications. Confirm that the device meets the necessary automotive quality certifications for your specific application tier. Ensure compatibility with your board's thermal management requirements given the QFN package type. Cross-reference the datasheet revision date to ensure all latest electrical characteristics are considered during final validation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Choose this component when a fixed 3.3V output is required without external feedback resistor networks. It is suitable for designs prioritizing simplicity and reduced bill-of-materials count. Consider the 2.2MHz switching frequency for minimizing inductor size compared to lower-frequency alternatives. Evaluate the 1.5A current limit against peak load demands to prevent triggering protection circuits under transient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to Texas Instruments' TPS62xxx family of automotive step-down converters.
