Overview
The LT3782AEFE is a current mode two-phase step-up DC/DC converter controller from Analog Devices. It operates with an input voltage range of 6V to 40V and supports adjustable output voltages. The device features a switching frequency up to 500kHz, reducing external filter requirements. It provides a 4A peak gate drive current and maintains a low static current of 40uA. The component is housed in a 28-TSSOP package with an exposed pad and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Two-phase operation reduces system filtering component requirements
- High switching frequency capability up to 500kHz
- Current mode control architecture for precise regulation
Applications
- Automotive-grade power supply systems
- Industrial DC/DC conversion applications
- Battery-powered equipment requiring high efficiency
Procurement Notes
Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for specific electrical characteristics. Ensure storage conditions meet manufacturer specifications to prevent degradation. Validate supplier documentation against official Analog Devices records.
Selection Notes
Select this controller for designs requiring dual-phase boost topology with high frequency operation. Consider the 28-TSSOP package constraints for PCB layout. Evaluate thermal management needs given the exposed pad requirement. Assess input voltage stability within the 6V to 40V operational window. Verify compatibility with external MOSFETs for the 4A drive capability.
Part Context
This component belongs to the LT3782 family of power management ICs designed for high-efficiency step-up conversions. It serves as a specialized controller rather than a complete integrated switcher. The device complements other Analog Devices PMIC solutions by offering dedicated phase control. It targets applications demanding compact size and reduced passive component counts.
Replacement Considerations
LT3782AEFE#PBF is listed as a direct substitute. LT3782AFE#PBF may serve as an alternative depending on specific grade requirements. Verify pinout and electrical parameter compatibility before substitution. Consult official Analog Devices documentation for cross-reference validation.
