LTC3862EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3862EUH#TRPBF is a dual-output DC/DC switching controller manufactured by Analog Devices Inc., designed for boost and SEPIC topologies. It operates with an input supply voltage range of 5.5V to 36V and supports two positive outputs. The device features adjustable switching frequencies between 75kHz and 500kHz, with a maximum duty cycle of 96%. It is housed in a 24-WQFN package with exposed pad (5x5mm) and functions within a temperature range of -40°C to 85°C.

DC DC Switching Controllers Feature Summary

• Supports both Boost and SEPIC converter topologies for versatile power conversion applications
• Provides independent control for two separate output channels
• Includes integrated phase control capabilities for synchronized multi-phase operation

DC DC Switching Controllers Applications

• Dual-rail power distribution systems requiring isolated or non-isolated step-up regulation
• Industrial equipment utilizing SEPIC converters for wide input voltage ranges
• Battery-powered devices needing efficient voltage boosting from lower cell voltages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the EUH package designation matches your PCB footprint requirements. Ensure the component meets RoHS compliance standards for your manufacturing process. Check current availability status as supply may be restricted. Validate that the operating temperature range suits your environmental conditions.

DC DC Switching Controllers Selection Notes

Select this controller when dual-channel boost or SEPIC regulation is required. Consider the 5.5V minimum supply voltage against your system's lowest operating point. Evaluate the 75kHz to 500kHz frequency range for inductor size versus efficiency trade-offs. Verify compatibility with external MOSFETs for the desired current levels. Ensure the 24-QFN package fits within your board space constraints.

DC DC Switching Controllers Part Context

This component belongs to the LTC3862 family of dual-output controllers. It is distinct from buck-only regulators like the LTC3868. The part integrates driver circuitry for external switches rather than containing internal power stages. It serves as a central management unit for complex power architectures requiring multiple stepped-up rails.

DC DC Switching Controllers Replacement Considerations

Direct replacements include other parts from the LTC3862 series with compatible packages. Cross-reference pinouts carefully when considering alternative manufacturers. Verify that substitute components support both Boost and SEPIC modes if both are utilized in the design.
