LTC3896HFE

DC DC Switching Controllers Overview

The LTC3896HFE#PBF is a high-performance inverting DC/DC switching regulator controller manufactured by Analog Devices Inc. It converts a wide-range positive input voltage source into a regulated negative output, capable of reaching up to 60V below ground. The device drives an all N-channel synchronous power MOSFET stage. Key electrical parameters include an input voltage range of 4V to 150V and a maximum output current of 2A. The static current is specified at 40uA, with a switch frequency of 900kHz. It operates within a temperature range of -40°C to +150°C and is housed in a TSSOP-EP-38 package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the TSSOP-EP-38 package dimensions match your PCB footprint requirements. Ensure the 150V input rating aligns with your system's maximum transient voltage levels. Check for availability constraints as distribution status may vary by region. Validate that the 2A output current capability meets your load requirements under all operating conditions.

DC DC Switching Controllers Selection Notes

Select this component when a single-phase inverting topology is required for high-voltage inputs. It is suitable for applications demanding low quiescent current during standby modes. Consider the 900kHz switching frequency for balancing component size and efficiency. Ensure the thermal performance of the TSSOP-EP-38 package supports your heat dissipation strategy. Verify compatibility with external N-channel MOSFETs for the synchronous rectification stage.

DC DC Switching Controllers Part Context

The LTC3896 belongs to Analog Devices' family of high-voltage DC/DC controllers designed for robust industrial and commercial applications. Unlike buck or boost converters, this specific model specializes in inverting topologies, providing negative regulation from positive inputs. It shares architectural similarities with other LTC38xx series devices but is distinct in its inverting function and high-voltage input handling capabilities.
