LTC3808EGN#TRPBF

DC DC Switching Controllers Overview

The LTC3808EGN#TRPBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 750 kHz and accepts an input voltage range from 2.75 V to 9.8 V. The device supports output voltages between 600 mV and 9.8 V, capable of driving up to 5 A. Key electrical parameters include a quiescent current of 105 uA and a supply current of 350 uA. It is housed in a 16-lead SSOP package and functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Eliminates the need for external sense resistors through proprietary No RSENSE technology
• Incorporates Low EMI architecture to minimize electromagnetic interference emissions
• Provides precise output tracking capabilities for synchronized power rail sequencing

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial equipment
• Power distribution systems for embedded computing platforms
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., as legacy listings may reference Linear Technology. Ensure the component meets RoHS3 compliance standards required for modern assembly processes. Cross-reference the full part number against official distributor catalogs to avoid obsolete or non-compliant variants.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high efficiency without the cost and board space of current sense resistors. The integrated low EMI feature suits noise-sensitive applications where filtering components must be minimized. Verify that the 750 kHz frequency aligns with thermal constraints and inductor selection requirements for the target load current.

DC DC Switching Controllers Part Context

This component belongs to the LTC3808 family of synchronous buck controllers. It shares core architectural features with other members like the LTC3808EDE but differs in package type and manufacturing lot specifications. The EG suffix denotes the SSOP package variant, distinguishing it from DFN options within the same functional series.
