LTC3892IFE-1#TRPBF

DC DC Switching Controllers Overview

The LTC3892IFE-1#TRPBF is a high-performance dual step-down DC/DC switching regulator controller designed to drive all N-channel synchronous power MOSFET stages. It operates with an input voltage range of 4.5V to 60V and supports output voltages from 800mV to 59.4V. The device delivers up to 25A of total output current across two phases. Key electrical parameters include a quiescent current of 34µA, a programmable switching frequency between 105kHz and 835kHz, and operation within a temperature range of -40°C to +125°C. It utilizes a 28-TSSOP-EP package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm availability status as the base part number may have discontinuation notices. Ensure the supplier provides official Analog Devices documentation to validate the component's authenticity and revision level before integration into production designs.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring wide input voltage ranges up to 60V and high current capabilities. Consider the 28-TSSOP-EP package for thermal management requirements. Evaluate the need for out-of-phase operation to reduce input ripple. Verify that the chosen external MOSFETs are compatible with the gate drive specifications provided in the datasheet.

DC DC Switching Controllers Part Context

This component belongs to the LTC3892 family of dual output synchronous step-down controllers from Analog Devices. It shares core architecture with variants like the LTC3892EFE-1 but differs in package type and specific ordering suffixes. The family is designed for versatile power management solutions in demanding industrial and communication environments.

DC DC Switching Controllers Replacement Considerations

LTC3892IFE-1#PBF is listed as a direct substitute. Verify pinout and electrical specifications match exactly. Check for any changes in packaging or moisture sensitivity levels between the tape and reel and tube options.
