LT3514HFE#PBF

Overview

The LT3514HFE#PBF is a triple step-down switching regulator manufactured by Analog Devices Inc. It features three independent adjustable outputs with maximum currents of 2A, 1A, and 1A respectively. The device operates from an input voltage range of 3.2V to 36V and supports a switch frequency between 270kHz and 2.1MHz. It utilizes a 24-TSSOP package with an exposed pad for thermal management and functions as a non-synchronous buck converter.

Feature Summary

Integrates three independent high-current buck regulators in a single compact package
Supports wide input voltage ranges suitable for various power supply architectures
Allows flexible output voltage configuration through external resistor networks

Applications

Multi-rail power distribution systems requiring simultaneous negative voltage generation
Industrial control boards needing isolated or distinct analog and digital power rails
Embedded systems utilizing multiple voltage domains for mixed-signal processing

Procurement Notes

Verify the specific suffix HFE against official Analog Devices documentation to confirm pinout and thermal specifications. Ensure compatibility with the required operating temperature range and package dimensions before integration into the design.

Selection Notes

Select this component when a design requires three separate regulated outputs from a single controller to minimize board space. Consider the non-synchronous topology efficiency requirements and the need for external Schottky diodes compared to synchronous alternatives.

Part Context

This part belongs to the LT3514 family of triple-output DC-DC converters designed for applications requiring multiple power rails. It serves as a solution for reducing component count in systems that previously utilized discrete regulators for each voltage domain.
