LTC3896HFE#TRPBF

DC DC Switching Controllers Overview

The LTC3896HFE#TRPBF is a synchronous inverting DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 150 V and delivers up to 2 A output current. The device supports an adjustable output voltage from 800 mV to 60 V. Key electrical parameters include a quiescent current of 40 uA, a fixed switching frequency of 900 kHz, and a shutdown supply current of 40 uA. It functions within a temperature range of -40°C to +150°C and utilizes a TSSOP-EP-38 package.

DC DC Switching Controllers Feature Summary

• Synchronous inverting topology for negative voltage generation
• Low quiescent current operation for enhanced efficiency
• Wide input voltage capability supporting high-voltage sources

DC DC Switching Controllers Applications

• Industrial systems requiring isolated or non-isolated negative rails
• Telecommunications equipment power management
• High-voltage sensor biasing circuits

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm the H-grade designation matches required thermal performance specifications. Ensure compatibility with the designated development kit DC2447A for initial validation. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a stable negative voltage derived from a positive high-voltage rail. The fixed 900 kHz frequency allows for compact passive component selection. Consider the TSSOP-EP-38 package for thermal dissipation requirements. Verify that the 2 A output current meets the load demands of the target circuit design.

DC DC Switching Controllers Part Context

This part belongs to the LTC3896 series of low IQ synchronous inverting DC/DC controllers. It is designed to simplify the generation of negative voltages from existing positive bus lines. The series emphasizes high efficiency and minimal standby power consumption in demanding industrial environments.

DC DC Switching Controllers Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Do not assume functional equivalence with other buck or boost controllers without schematic verification.
