LT3692AHUH#TRPBF

Overview

The LT3692AHUH#TRPBF is a dual current mode PWM step-down DC/DC converter featuring two internal 3.8A switches. It supports an input voltage range of 3V to 36V and provides independent output voltages adjustable from 0.8V to 34.2V per channel. The device operates with a fixed switching frequency of 2.5MHz and includes comprehensive protection features such as UVLO, soft-start, and current limiting. Designed for automotive applications, it utilizes a 32-pin QFN EP package.

Feature Summary

Dual-channel synchronous buck architecture with independent control pins for complex power sequencing
Integrated 3.8A internal switches supporting high-current single or multi-output configurations
Automotive-grade reliability with extended temperature performance capabilities

Applications

Complex power supply tracking and sequencing requirements
Multi-rail system power distribution in automotive electronics
Synchronous step-down conversion for digital loads requiring precise voltage regulation

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the component meets required automotive qualification standards and validate thermal dissipation requirements for the QFN EP package under intended load conditions.

Selection Notes

Select this model when independent channel control and high current density are required. The dual-switch topology allows flexible output combinations. Consider the 2.5MHz frequency for smaller passive components. Verify that the 36V maximum input rating aligns with the system supply rails and that the 3.8A switch current capability suffices for peak load demands.

Part Context

This component belongs to the LT3692 family of monolithic dual tracking switching regulators. It shares architectural similarities with variants like the LT3692IUH and LT3692EUH but differs in specific automotive grading and package options. The AHUH variant specifically targets robust industrial and automotive environments requiring high efficiency and compact form factors.
