LTC7840EUFD#TRPBF

DC DC Switching Controllers Overview

The LTC7840EUFD#TRPBF is a dual-phase, dual-output non-synchronous boost controller manufactured by Analog Devices Inc. It operates within a supply 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 includes hiccup mode protection. It is housed in a 28-lead QFN package and is rated for operation between -40°C and +125°C.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture supporting two independent outputs
• Constant frequency current mode control topology
• Integrated hiccup mode for fault protection
• Non-synchronous design suitable for high-voltage boost applications

DC DC Switching Controllers Applications

• High-voltage DC/DC conversion systems
• Industrial power supplies requiring dual isolated or non-isolated outputs
• Battery-powered equipment with boost requirements
• Automotive electronics utilizing wide input voltage ranges

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the EUFD package variant matches your PCB footprint requirements. Ensure compatibility with the 5.5 V to 60 V input range for your target application. Check for RoHS3 compliance status if required by your manufacturing standards. Validate that the non-synchronous nature aligns with your efficiency targets.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring dual independent boost outputs from a single controller. Consider the 5.5 V to 60 V operating range against your source voltage. Evaluate the 50 kHz to 425 kHz frequency range for inductor sizing. Account for the non-synchronous topology when calculating thermal performance. Verify the 28-QFN package dimensions fit your assembly constraints.

DC DC Switching Controllers Part Context

This part belongs to the LTC7840 family of dual-phase boost controllers. It complements other Analog Devices PMICs by providing multi-output solutions without requiring multiple separate controllers. The device integrates essential protections and control loops into a compact form factor, reducing bill of materials count compared to discrete implementations.
