LTC3896IFE

DC DC Switching Controllers Overview

The LTC3896IFE is a high-performance inverting DC/DC switching regulator controller manufactured by Analog Devices Inc. It is designed to drive an all N-channel synchronous power MOSFET stage, converting a wide-ranging positive input voltage source into a regulated negative output that can extend up to 60V below ground. The device supports input voltages ranging from 36V to 72V and provides a typical -48V output at 2A current capability. It operates within a junction temperature range of -40°C to 125°C and is housed in a 28-lead TSSOP package with an exposed pad for thermal management.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with the intended application requirements. Confirm RoHS compliance status and check for any recent product change notifications or obsolescence notices directly from Analog Devices before finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this component when designing inverting topologies that require driving synchronous N-channel MOSFETs from a positive input to generate a substantial negative voltage. Ensure the input voltage range aligns with the 36V to 72V specification and that the thermal design accommodates the TSSOP-EP package characteristics for reliable operation under load.

DC DC Switching Controllers Part Context

The LTC3896 belongs to a family of high-performance DC/DC controllers from Analog Devices, specifically tailored for complex power management applications. Unlike standard buck or boost controllers, this model focuses on inverting configurations, providing a specialized solution for generating negative rails in systems where positive-to-negative conversion is required with high efficiency and precise regulation.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3896HFE#PBF, which shares the same functional specifications but may differ in temperature grade or packaging variations. Verify pinout compatibility and electrical parameters against the official datasheet before implementing any replacement.
