LTC3895IFE#TRPBF

DC DC Switching Controllers Overview

The LTC3895IFE#TRPBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 140 V and delivers up to 10 A of output current. The device supports adjustable output voltages from 800 mV to 60 V. Key electrical parameters include a fixed switching frequency of 900 kHz, a quiescent current of 40 uA, and a load regulation of 0.01%. It is housed in a TSSOP-EP-38 package and functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports high-voltage inputs up to 140 V for flexible power distribution architectures
• Integrates low quiescent current operation to enhance efficiency during light-load conditions
• Provides precise output voltage regulation with minimal load regulation error

DC DC Switching Controllers Applications

• Industrial power supplies requiring wide input voltage ranges
• Telecommunications infrastructure equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and package type against official datasheets to ensure compatibility with your design requirements. Confirm availability status as supply may be limited or subject to allocation. Ensure all environmental compliance certifications match your project specifications before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Select this component when designing systems that require high input voltage tolerance combined with moderate output current capabilities. The fixed 900 kHz switching frequency allows for compact passive component selection. Consider thermal management requirements due to the TSSOP-EP-38 package exposure pad for heat dissipation.

DC DC Switching Controllers Part Context

This part belongs to the LTC3895 series of synchronous buck controllers designed for high-voltage applications. It is distinct from lower-voltage counterparts like the LTC3890 and offers higher input voltage capability compared to standard 60 V controllers. The IFE suffix indicates a specific temperature grade and packaging configuration within the Analog Devices portfolio.
