Overview
The LT3782AEFE#TRPBF is a dual-phase step-up DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 6 V to 40 V and supports switching frequencies from 150 kHz to 500 kHz. The device provides a peak drive current of 4 A with a 10 V gate drive capability when VCC is at least 13 V. It features adjustable output voltage, low static current of 40 uA, and operates between -40°C and +125°C. Packaged in a TSSOP-EP-28 housing, it includes shutdown functionality and is designed for efficient power conversion in industrial applications.
Feature Summary
- Dual-phase operation reduces system filtering requirements for capacitors and inductors
- High peak drive current of 4 A efficiently powers industrial-grade MOSFETs
- Adjustable switching frequency allows optimization for specific design constraints
Applications
- LED driver circuits
- Industrial power supply systems
- General-purpose step-up DC/DC conversion
Procurement Notes
Verify the exact suffix against official Analog Devices documentation to confirm package type and reel specifications. Ensure compatibility with required thermal management solutions given the operating temperature range. Cross-reference pinout details with the latest datasheet revision to avoid integration errors during PCB layout.
Selection Notes
Choose this component when high efficiency and reduced passive component count are critical. The dual-phase architecture suits applications requiring significant current handling without excessive heat generation. Consider the 10 V gate drive requirement to ensure proper MOSFET selection for optimal performance.
Part Context
This part belongs to the LT3782A series of dual-phase boost controllers. It shares functional similarities with other members of the family but differs in packaging and tape/reel configuration. The FE#TRPBF suffix indicates a specific surface-mount variant optimized for automated assembly processes.
Replacement Considerations
LT3782AIFE#PBF serves as a tube-pack alternative within the same series. Verify electrical parameters remain identical before substitution. Ensure mechanical footprint compatibility if replacing in existing designs.
