LTC3834EFE#PBF

DC DC Switching Controllers Overview

The LTC3834EFE#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc., designed for high-efficiency power conversion in automotive and industrial applications. It operates with an input voltage range of 4V to 36V, supporting output currents up to 25A. The device features a low quiescent current of 30µA and a fixed switching frequency of 400kHz. It provides adjustable output voltages from 800mV to 10V with a load regulation of 0.1%. Packaged in a 16-lead SSOP with exposed pad, it functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (EFE vs IFE) against the required package type and temperature rating. Confirm RoHS compliance status through official documentation. Ensure the supplier provides traceability data for automotive applications. Cross-reference the datasheet revision to confirm pinout compatibility. Validate that the component meets the specific environmental standards required for the target deployment.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 36V is required alongside high output current capabilities. The fixed 400kHz frequency offers a balance between size and efficiency. Consider the SSOP package constraints for PCB layout. Evaluate the need for external compensation components based on the desired transient response. Compare against lower-current alternatives if the 25A limit exceeds system requirements.

DC DC Switching Controllers Part Context

This component belongs to the LTC3834 family of synchronous step-down controllers. It shares functional similarities with other members like the LTC3834EGN-1#PBF but differs in package and specific electrical characteristics. The EFE variant specifically denotes the SSOP-16 package configuration. It is part of Analog Devices' broader portfolio of power management integrated circuits focused on high-performance DC/DC conversion.
