Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm RoHS compliance details and specific packaging requirements prior to order placement. Ensure the 10-MSOP-EP footprint matches design specifications. Check for recent production change notifications affecting pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select this controller when designing circuits requiring inputs up to 100V with flexible topology options. Consider the 10-MSOP-EP package for space-constrained applications needing exposed pad thermal dissipation. Evaluate the -40°C to +150°C junction temperature range against environmental conditions. Compare against LT3758 variants if different temperature grades or packaging formats are required for specific manufacturing needs.

Part Context
