LT3694EFE-1#PBF

Overview

The LT3694EFE-1#PBF is a monolithic switching regulator featuring one adjustable buck converter and two low-dropout linear regulators. It operates from an input voltage range of 4V to 36V with a maximum buck output current of 2.6A. The buck section supports frequencies between 250kHz and 2.5MHz, while the dual LDOs provide independent outputs. The device is housed in a 20-pin TSSOP package with exposed pad and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-current synchronous buck converter alongside two independent LDOs for combined power management
Offers wide input voltage compatibility suitable for industrial and automotive bus architectures
Provides flexible frequency synchronization capabilities to optimize external component size

Applications

Industrial equipment requiring multiple regulated voltage rails
Automotive infotainment and control modules
Telecommunications infrastructure power distribution

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics match the required design specifications. Ensure the package type aligns with thermal management requirements. Confirm RoHS compliance status through the manufacturer's declaration before finalizing procurement orders.

Selection Notes

Select this component when a single solution is needed to generate both high-current switching and precision linear voltages. Evaluate the total available current budget across all three outputs to ensure it meets system demands. Consider the thermal performance of the TSSOP-EP package for the intended operating environment.

Part Context

This part belongs to the LT3694 family of integrated power management ICs designed to simplify board space-constrained designs. It consolidates DC/DC and LDO technologies into a single chip, reducing the bill of materials and assembly complexity compared to discrete solutions.
