LT3782AIFE#PBF

Overview

The LT3782AIFE#PBF 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 switching frequency between 150 kHz and 500 kHz, delivering a peak output current of 4 A per phase. It utilizes a TSSOP-EP-28 package for surface mount installation. Electrical specifications include a static current of 40 uA and a working supply current of 11 mA. The component functions within a temperature range of -40 C to +125 C.

Feature Summary

Implements current mode control architecture for precise regulation in two-phase boost configurations
Utilizes high-frequency operation up to 500 kHz to minimize external passive component requirements
Provides integrated 10V gate drive capability for efficient synchronous rectifier control

Applications

Industrial power supply systems requiring multi-phase boost conversion
Battery-powered equipment needing efficient voltage step-up from low input sources
Telecommunications infrastructure utilizing standard bus voltage levels

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm availability status as distribution channels may report limited stock or restricted supply conditions. Ensure the TSSOP-EP-28 thermal pad connection is properly handled during assembly. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision history before procurement.

Selection Notes

Select this controller for designs requiring reduced magnetic component size through high-frequency two-phase interleaving. Consider the 40 V maximum input limit and 72 V output capability when defining circuit boundaries. Evaluate the 150 kHz to 500 kHz frequency range against electromagnetic interference constraints. Verify that the TSSOP-EP-28 package footprint matches the printed circuit board layout requirements for adequate thermal dissipation.

Part Context

This component belongs to the LT3782A series of power management integrated circuits designed for high-efficiency DC/DC conversion. It serves as a specialized controller rather than a complete regulator, requiring external MOSFETs and inductors. The series targets applications demanding compact solutions with improved transient response capabilities compared to single-phase alternatives.
