LTC7840IFE#PBF

DC DC Switching Controllers Overview

The LTC7840IFE#PBF is a dual-phase, dual-output non-synchronous boost controller manufactured by Analog Devices Inc. It operates within an input voltage range of 5.5 V to 60 V and supports switching frequencies from 50 kHz to 425 kHz. The device features a maximum duty cycle of 96% and provides two independent outputs with a control voltage limit of 10 V. Packaged in a QFN-28 form factor for surface mount installation, it functions as a non-isolated power management IC. The component is rated for industrial temperatures ranging from -40°C to +150°C.

DC DC Switching Controllers Feature Summary

• Supports dual-phase, dual-output non-synchronous boost topologies
• Enables flexible frequency synchronization across a wide range
• Integrates shutdown functionality for power management

DC DC Switching Controllers Applications

• High voltage DC/DC conversion systems
• Industrial power supply designs
• Automotive electronics applications

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'IFE' indicates the TSSOP-28 package variant rather than the QFN-28 configuration found in other LTC7840 models. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the ordering part number matches the required pinout and thermal characteristics for the target PCB layout.

DC DC Switching Controllers Selection Notes

Select this component when a dual-output high-voltage boost solution is required without synchronous rectification. Compare against the LTC7840HUFD#PBF if a QFN-28 package is preferred over the TSSOP-28 format. Evaluate the 5.5 V to 60 V input range against system requirements. Consider the 150°C maximum junction temperature for high-thermal environments.

DC DC Switching Controllers Part Context

This part belongs to the LTC7840 series of switching controllers designed for high-voltage applications. It complements other variants like the LTC7840HFE#TRPBF which shares similar electrical specifications but differs in packaging and reel quantity. The series addresses needs for efficient power conversion in demanding industrial and automotive sectors.

DC DC Switching Controllers Replacement Considerations

The LTC7840HFE#TRPBF serves as a functional substitute with identical electrical performance but utilizes a TSSOP-28 package and tape-and-reel shipping. Verify package compatibility and reflow profile differences between tube and reel formats during replacement planning.
