LT3692AHUH#PBF

Overview

The LT3692AHUH#PBF is an automotive-grade, dual current mode PWM step-down DC/DC converter featuring two internal 3.8A switches. It operates with an input voltage range of 3V to 36V and provides a synchronous output adjustable from 0.8V to 34.2V at up to 3.5A. The device integrates independent control pins for each channel, including input voltage, shutdown, feedback, soft-start, UVLO, current limit, and comparator functions. This architecture facilitates complex power supply tracking and sequencing requirements in demanding environments.

Feature Summary

Dual-channel architecture with independent control pins simplifies complex power supply tracking and sequencing.
Automotive-grade reliability designed for harsh operating conditions.
Integrated soft-start and under-voltage lockout (UVLO) ensure controlled startup and protection.

Applications

Automotive infotainment systems requiring synchronized multi-rail power.
Industrial controllers needing precise voltage tracking between rails.
Complex embedded systems with strict power-up sequencing constraints.

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm automotive qualification and package type. Ensure the ordering part number matches the required temperature grade and pin configuration. Cross-reference datasheet revisions to validate feature availability. Confirm RoHS compliance status through manufacturer declarations. Validate supplier authenticity via authorized distribution channels.

Selection Notes

Select this component when dual isolated or tracked outputs are required within a single footprint. The independent channel controls allow flexible configuration for different voltage levels. Consider the 3.8A switch capability for high-current applications. Verify thermal performance requirements for the QFN-32 package. Ensure input voltage ranges align with system bus specifications.

Part Context

This part belongs to the LT3692 family of monolithic dual tracking switching regulators. It shares core topology with non-automotive variants but includes enhanced durability specifications. The family supports various output configurations through external resistor networks. It serves as a compact solution for replacing multiple discrete regulator components.
