LT3692AIFE#PBF

Overview

The LT3692AIFE#PBF is a monolithic dual tracking 3.5A step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 36V and delivers two independent outputs adjustable from 800mV to 34.2V, each capable of sourcing up to 3.5A. The device utilizes a 2.5MHz fixed switching frequency and features a TSSOP-EP-38 package. It includes independent control pins for shutdown, feedback, soft-start, UVLO, and current limit, facilitating complex power supply sequencing.

Feature Summary

Dual channel architecture with independent control pins for simplified power supply tracking and sequencing requirements
Integrated high-frequency PWM operation enabling compact passive component selection
Comprehensive protection mechanisms including independent current limiting and under-voltage lockout per channel

Applications

Complex multi-rail embedded systems requiring synchronized power-up sequences
Industrial equipment needing independent voltage regulation for mixed-signal circuits
Telecommunications infrastructure utilizing dual tracking buck converters

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging configuration. Confirm the TSSOP-EP-38 thermal pad soldering requirements during assembly. Ensure the design accounts for the 2.5MHz switching frequency noise characteristics in sensitive analog sections.

Selection Notes

Select this component when dual independent outputs are required from a single IC footprint. It is suitable for designs needing precise tracking between two voltage rails without external synchronization circuitry. Consider the 3.5A per channel rating against total system load demands.

Part Context

This part belongs to the LT3692A family of dual synchronous buck regulators. It shares architectural similarities with other members like the LT3692AHFE but differs in output current capabilities and specific feature sets such as UVLO/OVLO integration found in variant AHFE models.
