LT3782EFE

Overview

The LT3782EFE is a current-mode two-phase step-up DC/DC converter controller manufactured by Analog Devices Inc. It operates within an input voltage range of 6V to 40V and supports switching frequencies from 154kHz to 465kHz. The device features a maximum duty cycle of 94% and includes integrated synchronous rectification. It is housed in a 28-TSSOP-EP package with an exposed pad for thermal management. The controller provides positive output configuration with two outputs and two output stages, designed for high-efficiency power conversion applications.

Feature Summary

Two-phase operation reduces system component count and ripple currents
Integrated synchronous rectification for improved efficiency
Current mode control architecture for fast transient response
Clock synchronization capability for multi-unit phase shedding

Applications

Industrial power supplies
Telecommunications infrastructure
Automotive electronics

Procurement Notes

Verify the specific suffix and tape/reel or tube packaging requirements against the official datasheet before ordering. Confirm that the 28-TSSOP-EP footprint matches your PCB design constraints. Ensure compatibility with the required operating temperature range of -40°C to 125°C. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this controller when a compact, high-frequency boost solution is required. The two-phase topology is suitable for applications demanding higher output currents without excessive input ripple. Consider the 6V to 40V input range for compatibility with various bus voltages. Evaluate thermal performance due to the exposed pad requirement for adequate heat dissipation.

Part Context

The LT3782EFE belongs to the LT3782 family of dual-phase step-up DC/DC controllers. It is designed to replace single-phase solutions by halving the input and output capacitor requirements. The device integrates the necessary drivers for external N-channel MOSFETs, simplifying the bill of materials. It is part of Analog Devices' portfolio of high-performance power management ICs.
