LT3782AIFE#TRPBF

Overview

The LT3782AIFE#TRPBF is a current mode, two-phase step-up DC/DC converter controller manufactured by Analog Devices Inc. It operates with an input voltage range of 6 V to 40 V and supports adjustable output voltages up to 72 V. The device features a programmable switching frequency from 150 kHz to 500 kHz and delivers a high-current gate drive of 4 A. It utilizes a TSSOP-EP-28 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Two-phase operation reduces system filtering requirements for capacitors and inductors
• High switching frequency capability up to 500 kHz
• Synchronous rectification with high-current gate driver

Applications

• High-density power supply designs
• Industrial equipment power management
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm availability status as distribution channels may list limited stock or special order conditions. Ensure the component matches the required thermal and electrical specifications for the target application environment before finalizing procurement.

Selection Notes

Select this controller for applications requiring reduced passive component size due to high-frequency two-phase operation. Consider the 6 V to 40 V input range and 72 V output capability for suitable voltage conversion needs. Evaluate the TSSOP-EP-28 package for thermal performance and board space constraints relative to alternative packages.

Part Context

This part belongs to the LT3782A series of synchronous boost controllers. It is designed for efficient power conversion in compact systems. The device integrates necessary control logic for two-phase interleaved operation, enhancing efficiency and reducing ripple compared to single-phase solutions.

Replacement Considerations

LT3782AIFE#PBF is a verified substitute offering identical functionality in tube packaging instead of tape and reel.
