LT3692AEFE#PBF

Overview

The LT3692AEFE#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 up to 3.5A output current per channel. The device utilizes a fixed 2.5MHz switching frequency and supports adjustable output voltages from 800mV to 34.2V. Packaged in a TSSOP-EP-38 surface-mount format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Dual current mode PWM architecture with independent control pins for each channel
• Integrated soft-start, undervoltage lockout, and comparator functionality
• Supports complex power supply sequencing and tracking requirements

Applications

• Complex power supply tracking applications
• Output sequencing systems
• External synchronization circuits

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the TSSOP-EP-38 package dimensions against your PCB footprint library. Ensure the design accommodates the specified thermal requirements for the operating temperature range. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Selection Notes

Select this component when dual-channel buck regulation with precise tracking is required. The independent shutdown and feedback pins allow for customized sequencing without external logic. Verify that the 3.5A current rating meets the load demands of both channels simultaneously under worst-case conditions.

Part Context

This device belongs to the LT3692A series of monolithic dual tracking regulators. It is designed for applications requiring synchronized outputs or specific startup sequences. The integrated nature reduces the component count compared to discrete solutions, simplifying board layout while maintaining high efficiency.
