Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix QPWR against official Texas Instruments documentation to confirm tape-and-reel packaging configuration. Ensure the component meets AEC-Q100 grade requirements for your target application environment. Cross-reference the full part number with authorized distributors to validate authenticity and supply chain integrity before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems that require a combined buck and fly-buck solution from a high-voltage source. The 1 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 100 V maximum input rating to ensure compatibility with automotive load dump conditions and wide-range power buses.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM5161 family of wide-input synchronous converters. It complements other Texas Instruments automotive-grade power management ICs by offering dual topology flexibility. The part is distinct from standard buck-only regulators due to its ability to drive isolated outputs via the fly-buck mode while maintaining synchronous rectification efficiency.
