LTC3838EFE#TRPBF

DC DC Switching Controllers Overview

The LTC3838EFE#TRPBF is a high-performance, dual-output step-down DC/DC controller from Analog Devices. It operates with an input voltage range of 4.5 V to 38 V and delivers up to 30 A per channel. The device features a fixed 2 MHz switching frequency and supports output voltages from 600 mV to 5.5 V. Key electrical specifications include a quiescent current of 15 uA and a load regulation of -1.5%. Designed for industrial applications, it functions within a temperature range of -40°C to +125°C and utilizes a QFN-38 package.

DC DC Switching Controllers Feature Summary

• Dual independent buck channels providing separate control for two distinct loads
• Integrated differential remote sensing inputs to maintain precise output voltage accuracy at the load point
• High-frequency 2 MHz operation enabling the use of compact external components

DC DC Switching Controllers Applications

• Industrial equipment requiring multiple regulated power rails
• Telecommunications infrastructure power distribution systems
• Embedded computing platforms needing high-current dual outputs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and thermal characteristics. Ensure the QFN-38 footprint matches your PCB layout requirements. Confirm that the operating temperature range meets your environmental standards before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated buck converters are required from a single input source. The differential sense feature is critical for applications where trace resistance causes significant voltage drop. Consider the 2 MHz frequency for balancing efficiency against passive component size constraints in space-limited designs.

DC DC Switching Controllers Part Context

This part belongs to the LTC3838 family of dual synchronous step-down controllers. It shares architectural similarities with other high-power PMICs but is distinguished by its dual-channel capability and integrated differential sensing. The device complements single-channel regulators like the LTC3833 by offering consolidated power management solutions.
