Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm AEC-Q100 qualification status if automotive reliability is required. Check datasheet for specific humidity sensitivity level requirements during soldering processes. Ensure input voltage does not exceed maximum ratings to prevent device damage. Validate thermal performance under expected load conditions before finalizing design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 65 V is necessary alongside moderate current delivery. Consider the integrated synchronous design for better efficiency compared to asynchronous alternatives. Evaluate the fixed 1 MHz frequency against EMI constraints and inductor size requirements. Ensure the HTSSOP-16 package fits the available PCB footprint. Verify that the operating temperature range meets the specific application environment demands.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5160 family of wide-input synchronous buck converters. It shares architectural similarities with other automotive-grade PMICs but distinguishes itself through its specific 65 V input tolerance and 2 A current capability. The QPWP suffix indicates automotive qualification and a specific surface-mount package variant. It complements lower-voltage regulators by handling higher bus voltages common in automotive architectures.
