LT3692EUH#TRPBF

Overview

The LT3692EUH#TRPBF is a dual synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 36V and provides two independent adjustable outputs ranging from 800mV to 34.2V. Each channel supports a maximum output current of 3.5A. The device features an adjustable switching frequency between 250kHz and 2.25MHz. It includes independent shutdown, feedback, soft-start, UVLO, and current limit controls for each channel. The component is housed in a QFN-32 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Dual-channel architecture with independent control pins for complex power sequencing
Adjustable switching frequency allows optimization for efficiency or size
Integrated synchronous rectification for high conversion efficiency

Applications

Complex multi-rail embedded systems requiring synchronized power tracking
Industrial equipment with distributed DC power requirements
Battery-powered digital devices needing efficient step-down regulation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging rather than tube. Confirm the exact operating temperature grade and electrical characteristics against the official Analog Devices datasheet for the LT3692 series. Ensure compatibility with the intended PCB footprint and thermal management strategy for the QFN-32 package.

Selection Notes

Select this component when dual isolated buck converters are required with independent timing and sequencing capabilities. It is suitable for designs where input voltages vary significantly between 3V and 36V. Consider the thermal dissipation requirements for the QFN-32 package when designing for maximum load currents near 3.5A per channel.

Part Context

This part belongs to the LT3692 family of dual synchronous buck regulators. It is designed to simplify power supply design by integrating two complete buck converters into a single compact package. The device eliminates the need for external catch diodes through internal synchronous rectification, reducing component count and board space.
