Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm that the 16-MSOP-EP package matches your PCB footprint requirements. Ensure compatibility with the 4.5V to 100V input range for your specific application. Check for any recent Product Change Notices regarding marking or material declarations before finalizing procurement.

Selection Notes

Select this component when a wide input voltage range up to 100V is required alongside flexible topology options. It is suitable for designs needing both positive and negative output capabilities from a single IC. Consider the 16-MSOP package size for space-constrained layouts. Verify that the 500mA switch current meets the load requirements for the chosen topology.

Part Context

This part belongs to the LT8331 family of high voltage DC/DC converters. It is designed for applications demanding flexibility in converter configuration without requiring multiple specialized ICs. The series is commonly used in industrial and automotive sectors where reliability and wide operating ranges are critical.
