LT3510EFE#TRPBF

Overview

The LT3510EFE#TRPBF is a dual-output synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.1 V to 25 V and provides two adjustable output channels, each capable of delivering up to 2 A of current. The device integrates high-side and low-side N-channel power switches within a TSSOP-20 package. It supports programmable switching frequencies between 250 kHz and 1.5 MHz and includes features such as tracking control, soft-start, and thermal shutdown for robust performance in space-constrained designs.

Feature Summary

• Dual independent adjustable outputs with integrated high-side and low-side N-channel power switches
• Synchronous buck topology supporting wide input voltage ranges from 3.1 V to 25 V
• Programmable switching frequency ranging from 250 kHz to 1.5 MHz for optimized efficiency and component size
• Includes tracking control capability allowing synchronized regulation of multiple rails

Applications

• Portable electronics requiring dual voltage rails
• Industrial control systems with distributed power architectures
• Communication equipment needing efficient step-down conversion
• Embedded systems utilizing space-saving surface-mount packages

Procurement Notes

Verify the specific suffix against official documentation, as #TRPBF indicates tape-and-reel packaging while #PBF denotes tube packaging. Confirm RoHS compliance status through the manufacturer's latest material declaration. Ensure the ordering part number matches the required package style and reel quantity specifications for your assembly process.

Selection Notes

Select this component when dual isolated or tracked outputs are required from a single converter stage. The integrated switch design reduces external component count compared to controller-based solutions. Consider the thermal performance of the TSSOP-20 package relative to the total load current and ambient operating conditions to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to the LT3510 family of dual synchronous buck regulators designed for high-efficiency power management. It shares architectural similarities with other Linear Technology-derived PMICs but distinguishes itself through its dual-channel capability and integrated power switches. The series targets applications demanding compact footprints and precise voltage regulation without external MOSFETs.

Replacement Considerations

Direct substitutes include the LT3510EFE#PBF for identical electrical characteristics in tube packaging. Verify pinout compatibility and thermal resistance values when considering alternative packages within the same product family.
