LTC3899EFE#TRPBF

DC DC Switching Controllers Overview

The LTC3899EFE#TRPBF is a low IQ triple output Buck/Buck/Boost synchronous controller from Analog Devices. It supports an input voltage range of 4.5 V to 60 V and delivers up to 15 A output current with voltages adjustable from 800 mV to 60 V. The device features a quiescent current of 39 uA and operates at switching frequencies between 105 kHz and 835 kHz. It provides load regulation of 0.01% and functions within a temperature range of -40°C to +125°C, housed in a 38-TSSOP-EP package.

DC DC Switching Controllers Feature Summary

• Integrates three independent channels combining two buck and one boost topology for versatile power rail generation.
• Features ultra-low static current consumption to minimize standby power loss in battery-operated systems.
• Supports wide input voltage ranges suitable for industrial and telecom bus architectures.

DC DC Switching Controllers Applications

• Industrial equipment requiring multiple isolated or non-isolated power rails
• Telecommunications infrastructure power distribution units
• Embedded systems with mixed voltage requirements

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the manufacturer is Analog Devices Inc. and check RoHS compliance status through official documentation before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when a single IC must manage three distinct power outputs including both step-down and step-up conversions. Ensure the design accommodates the 38-pin TSSOP thermal requirements and matches the required operating temperature range specifications.

DC DC Switching Controllers Part Context

This part belongs to the LTC3899 series of high-performance power management controllers. It is designed for applications needing compact solutions for complex multi-rail power architectures without requiring multiple discrete controller chips.

DC DC Switching Controllers Replacement Considerations

LTC3899IFE#PBF is a tube-packaged variant of the same functional controller. LTC3899MPFE#TRPBF offers military-grade temperature rating options within the same package family.
