LT3514IFE

Overview

The LT3514IFE is a triple step-down switching regulator IC manufactured by Analog Devices Inc. It operates with an input voltage range of 3.2V to 36V and provides three adjustable positive outputs, each capable of delivering up to 2A or 1A depending on the channel configuration. The device features a wide switching frequency range from 270kHz to 2.1MHz and supports 100% duty cycle operation for minimal dropout voltage. Packaged in a 24-TSSOP with exposed pad, it functions as a non-synchronous buck converter suitable for high-efficiency power management applications.

Feature Summary

Triple independent buck regulators providing separate output control
Wide input voltage range supporting diverse power sources
Adjustable output voltages starting from a 0.8V reference
High switching frequency capability for compact external component sizing

Applications

Industrial systems requiring multiple isolated or non-isolated voltage rails
Automotive electronics operating within specified input ranges
Telecommunications infrastructure power distribution units
Embedded computing platforms needing efficient DC-DC conversion

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required thermal dissipation methods due to the TSSOP-EP form factor. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through current material declarations provided by the manufacturer.

Selection Notes

Evaluate thermal performance requirements based on total output current and ambient conditions. Consider the impact of switching frequency selection on inductor size and efficiency. Verify that the minimum output voltage meets the lowest load requirement. Assess input voltage stability to ensure operation remains within the specified 3.2V to 36V window during transient events.

Part Context

This component belongs to the LT3514 family of triple synchronous buck regulators designed for high-density power solutions. It integrates control circuitry for three independent channels within a single compact package. The series targets applications demanding multiple regulated supplies from a single unregulated source, offering flexibility in system architecture design.
