LTC3871ILXE#PBF

DC DC Switching Controllers Overview

The LTC3871ILXE#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 input voltages from 1.2 V to 100 V and delivering up to 30 A output current. The device features a fixed 500 kHz switching frequency and low static current of 8 mA. Housed in an LQFP-48 package, it supports operation across a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Bidirectional operation allows seamless transition between buck and boost modes for flexible power flow control.
• Integrated synchronous rectification with programmable phase control for efficient multi-phase configurations.
• Supports clock synchronization and soft-start functionality to minimize inrush current and EMI.

DC DC Switching Controllers Applications

• High efficiency polyphase bidirectional charger supplies
• Industrial distributed power systems requiring reversible energy conversion
• Battery management systems with charge/discharge capabilities

DC DC Switching Controllers Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free RoHS compliance when ordering. Confirm availability status as distribution channels may report limited stock or discontinuation notices. Ensure the LQFP-48 package variant matches your PCB footprint requirements before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring bidirectional power flow control within a wide input voltage range. Consider the 500 kHz fixed frequency for standard filter sizing. Evaluate thermal performance in the LQFP-48 package for high-current scenarios exceeding 30 A if multiple phases are not utilized.

DC DC Switching Controllers Part Context

This part belongs to the LTC3871 series of PolyPhase controllers designed for versatile DC/DC conversion. It complements other Analog Devices power management ICs by offering bidirectional capability often found in battery-backed or regenerative systems. The ILXE designation specifies the industrial temperature grade and surface-mount packaging.
