LT3782IFE

Overview

The LT3782IFE is a current-mode two-phase boost DC/DC converter controller manufactured by Analog Devices Inc. It operates with a switching frequency range of 154kHz to 465kHz and supports a maximum duty cycle of 94%. The device features synchronous rectification and accepts an input voltage supply between 6V and 40V. It provides two positive output configurations via transistor drivers within a 28-TSSOP-EP package. The controller includes clock synchronization capabilities and supports operation temperatures from -40°C to 125°C TJ.

Feature Summary

Supports two-phase boost topology for reduced system filtering requirements
Features synchronous rectification for improved efficiency
Includes clock synchronization capability for multi-unit systems
Provides enable, reset, and soft-start control characteristics

Applications

High-efficiency step-up power supplies
LED driver circuits requiring precise current control
Battery-powered systems needing voltage boosting
Industrial equipment power management modules

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with required thermal dissipation standards for the TSSOP-EP footprint. Cross-reference RoHS compliance status with the latest manufacturer declarations prior to procurement. Confirm availability through authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing high-frequency boost converters requiring phase interleaving. Evaluate thermal performance based on the exposed pad design for adequate heat sinking. Consider the 6V to 40V input range relative to source voltage variations. Assess inductor and capacitor sizing needs derived from the 154kHz to 465kHz operating frequency range.

Part Context

This part belongs to the LT3782 family of dual-phase controllers designed for applications demanding high power density. It complements other PMIC solutions by offering synchronized multi-phase operation. The device integrates essential protection and control logic within a compact surface-mount package suitable for modern PCB layouts.
