LTC3892IFE-1#PBF

DC DC Switching Controllers Overview

The LTC3892IFE-1#PBF is a high-performance dual step-down DC/DC switching regulator controller manufactured by Analog Devices Inc. It drives all N-channel synchronous power MOSFET stages with an input voltage range of 4.5V to 60V and supports output voltages from 800mV to 59.4V. The device features a total output current capacity of 25A, a typical quiescent current of 34uA, and a switchable frequency range of 105kHz to 835kHz. Packaged in a 28-TSSOP-EP, it operates within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Minimizes power loss and noise through out-of-phase operation of two controller output stages

DC DC Switching Controllers Procurement Notes

Verify component authenticity and datasheet alignment when sourcing the LTC3892IFE-1#PBF. Note that the base part number LTC3892IFE-1 is listed as obsolete; ensure the #PBF suffix variant availability matches project requirements. Confirm package integrity and thermal pad soldering specifications for the 28-TSSOP-EP form factor prior to assembly integration.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring dual synchronous buck regulation with wide input voltage support up to 60V. The device is suitable where low quiescent current and phase-shifted operation are critical for efficiency. Ensure external components match the 105kHz to 835kHz frequency range and 25A total current capability constraints defined in the official specifications.
