DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct channels. Confirm RoHS compliance status via official documentation prior to integration. Ensure storage conditions meet manufacturer specifications to maintain reliability. Cross-reference ordering part numbers carefully to match exact suffix requirements for package and temperature grade variations.

DC DC Switching Controllers Selection Notes

Select this controller when designing inverting topologies requiring inputs up to 150 V. It is suitable for applications needing precise negative voltage regulation with minimal standby power consumption. Consider thermal management strategies given the TSSOP-EP-38 package and operating temperature limits. Evaluate external MOSFET selection to support the 2 A output current capability at the target switching frequency.

DC DC Switching Controllers Part Context

This component belongs to the LTC3896 series of inverting DC/DC controllers. It shares architectural similarities with other high-voltage power management ICs from Analog Devices but is distinctively optimized for generating stable negative voltages from positive sources. The HFE suffix indicates a specific temperature grade and package variant within the broader product family.
