LTC1874EGN#TRPBF

DC DC Switching Controllers Overview

The LTC1874EGN#TRPBF is a dual synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 550 kHz and supports an input voltage range from 2.5 V to 9.8 V. The device delivers up to 20 A output current per channel with adjustable output voltages. Packaged in SSOP-16, it features a quiescent current of 270 uA and includes shutdown functionality for power management.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture providing independent control for two separate buck converters
• Current mode control topology ensuring stable operation across varying load conditions
• Integrated shutdown pin allows for efficient system-level power management and standby modes

DC DC Switching Controllers Applications

• Portable computing systems requiring multiple regulated voltage rails
• Industrial equipment needing robust power distribution solutions
• Telecommunications infrastructure utilizing standard logic supply levels

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the SSOP-16 package variant matches your PCB footprint requirements. Ensure compatibility with the specified 2.5 V to 9.8 V input range for your target application design.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated outputs are required from a single controller IC. The 550 kHz frequency offers a balance between efficiency and external component size. Consider the 270 uA quiescent current for battery-operated devices where standby consumption is critical.

DC DC Switching Controllers Part Context

This part belongs to the LTC1874 series of high-efficiency synchronous step-down controllers. It is designed for applications requiring compact power solutions with minimal external component count. The dual-channel design simplifies board layout compared to using two separate single-channel controllers.
