LTC3871ELXE-1#PBF

DC DC Switching Controllers Overview

The LTC3871ELXE-1#PBF is a high-performance bidirectional buck or boost switching regulator controller from Analog Devices. It operates in either buck or boost mode on demand, supporting an input voltage range of 1.2 V to 100 V and delivering up to 30 A output current. The device features a fixed 500 kHz switching frequency and draws only 8 mA of quiescent current. It is housed in a 48-LQFP package with exposed pad and supports operation temperatures from -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Bidirectional control capability allowing seamless transition between buck and boost modes
• Wide input voltage range supporting diverse power source requirements
• Low quiescent current consumption for improved efficiency
• Integrated synchronous rectification drive

DC DC Switching Controllers Applications

• High efficiency polyphase bidirectional charger supplies
• Battery management systems requiring reversible power flow
• Industrial power conversion applications

DC DC Switching Controllers Procurement Notes

Verify the specific suffix '-1' against the official datasheet to confirm pinout or functional variations compared to standard variants. Ensure compatibility with required thermal management solutions given the LQFP-48 package. Confirm humidity sensitivity handling procedures during assembly as indicated by moisture sensitivity ratings.

DC DC Switching Controllers Selection Notes

Select this component when bidirectional power flow is required within a single controller architecture. The wide input voltage range suits applications with varying source voltages. Consider the 48-pin package size for PCB layout constraints. Verify that the 500 kHz frequency aligns with electromagnetic interference requirements and inductor selection goals.

DC DC Switching Controllers Part Context

This part belongs to the LTC3871 series of PolyPhase controllers designed for high-density power applications. It complements other devices in the family by offering bidirectional functionality, distinguishing it from unidirectional buck-only controllers. Development tools like DC2348A-A are available for performance evaluation.

DC DC Switching Controllers Replacement Considerations

LTC3871ILXE-1#PBF offers identical electrical specifications with potentially different temperature grading or packaging options. LTC3871ELXE#PBF lacks the '-1' suffix which may indicate pinout differences; verify schematics before substitution.
