LTC3838IUHF-2#TRPBF

DC DC Switching Controllers Overview

The LTC3838IUHF-2#TRPBF is a dual-output synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5 V to 38 V and supports output voltages from 600 mV to 5.5 V per channel. Each output delivers up to 30 A with a switching frequency adjustable between 200 kHz and 2 MHz. The device features a low quiescent current of 15 µA and operates over a temperature range of -40°C to +125°C. Packaged in a 38-pin QFN, it integrates synchronous rectification for high efficiency.

DC DC Switching Controllers Feature Summary

• Dual independent buck channels with integrated synchronous rectifiers

DC DC Switching Controllers Procurement Notes

Verify the specific suffix '#TRPBF' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the QFN-38 thermal pad soldering process meets PCB assembly standards for reliable operation under high current loads.

DC DC Switching Controllers Selection Notes

Select this component when dual high-current outputs are required from a single controller IC. The wide input range suits applications with varying supply voltages. Consider the 38-pin QFN package for space-constrained designs requiring efficient thermal dissipation. Verify that the external component selection supports the desired switching frequency and output current specifications.

DC DC Switching Controllers Part Context

This part belongs to the LTC3838 family of dual synchronous step-down controllers. It shares architectural similarities with the LTC3838IUHF-1#TRPBF but differs in pinout configuration or internal compensation settings. The series is designed for high-efficiency power management in compact form factors.

DC DC Switching Controllers Replacement Considerations

LTC3838IUHF-1#TRPBF serves as a functional alternative within the same family, though pin compatibility must be verified against the specific application schematic before substitution.
