LTC3789EUFD#PBF

DC DC Switching Controllers Overview

The LTC3789EUFD#PBF is a synchronous boost controller from Analog Devices, housed in a 28-lead QFN package. It operates with a supply voltage range of 4.5V to 60V and supports switching frequencies between 105kHz and 760kHz. The device features a maximum duty cycle of 96% and functions within an operating temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Synchronous boost topology for high efficiency
• Adjustable switching frequency control
• Integrated hiccup mode protection

DC DC Switching Controllers Applications

• Battery charging systems
• Power management circuits
• High voltage step-up converters

DC DC Switching Controllers Procurement Notes

Verify the specific datasheet revision corresponding to the EUFD suffix before design finalization. Confirm that the 28-QFN package dimensions align with your PCB footprint requirements. Ensure thermal relief pads are designed correctly for the exposed pad to maintain the specified junction temperature limits during operation.

DC DC Switching Controllers Selection Notes

Select this component when a dual-output synchronous boost solution is required with hiccup mode fault protection. It is suitable for applications needing wide input voltage ranges up to 60V. Consider the 28-QFN package for compact designs requiring efficient heat dissipation through the bottom pad.

DC DC Switching Controllers Part Context

This part belongs to the LTC3789 family of PolyPhase controllers. It is distinct from other variants like the LT3782A or LTC3784 by its specific dual-output architecture and hiccup mode functionality. The EUFD suffix denotes the industrial temperature grade and QFN packaging.
