LTC3808EGN#PBF

DC DC Switching Controllers Overview

The LTC3808EGN#PBF is a synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.75 V to 9.8 V and supports output voltages from 600 mV to 9.8 V. The device features a fixed switching frequency of 750 kHz and delivers up to 5 A of output current. It utilizes a No RSENSE architecture for high efficiency and low EMI generation. The component 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

• No RSENSE architecture eliminates external sense resistors to improve efficiency and reduce board space.
• Low EMI design incorporates spread spectrum modulation to minimize electromagnetic interference.
• Synchronous buck topology provides high conversion efficiency across the load range.
• Integrated output tracking capability allows synchronized regulation with other power rails.

DC DC Switching Controllers Applications

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

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., as generic listings may attribute the part to Linear Technology or NXP incorrectly. Ensure the SSOP-16 package matches the design requirements. Check for obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a compact synchronous buck solution without the need for current sense resistors. The 750 kHz switching frequency offers a balance between component size and efficiency. Verify that the input voltage range of 2.75 V to 9.8 V aligns with the system supply. Consider the 16-lead SSOP package constraints for thermal management and PCB layout space availability.

DC DC Switching Controllers Part Context

This component belongs to the LTC3808 family of synchronous DC/DC controllers designed for low noise and high efficiency applications. The EG suffix denotes the SSOP-16 plastic package variant, while the #PBF suffix confirms lead-free manufacturing. It serves as a direct replacement for older Linear Technology versions of the same functional specification.

DC DC Switching Controllers Replacement Considerations

LTC3808EGN#TRPBF is a tape-and-reel alternative offering identical electrical performance and pinout compatibility. Both variants share the same SSOP-16 package and functional specifications, differing only in shipping packaging format.
