LTC7815EUHF#PBF

DC DC Switching Controllers Overview

The LTC7815EUHF#PBF is a low quiescent current, triple-output synchronous controller from Analog Devices. It integrates two buck channels and one boost channel within a single package. The device supports switching frequencies up to 2.25 MHz and operates with a bias input voltage range of 4.5 V to 38 V. Output voltages are adjustable from 800 mV to 60 V. It utilizes a 38-lead QFN (5mm x 7mm) package with an exposed pad for thermal management. The component functions as a non-isolated power management IC suitable for point-of-load applications.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging versus TRPBF for reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the supplier provides valid traceability certificates. Check for obsolescence notices or lifecycle changes directly from Analog Devices before finalizing purchase orders.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring three independent regulated outputs from a single controller. The dual buck plus single boost topology simplifies board layout compared to using separate controllers. Consider the 38-lead QFN package constraints for thermal dissipation requirements. Verify that the required output current capabilities align with the external MOSFET selection for the specific application load conditions.

DC DC Switching Controllers Part Context

This part belongs to the LTC7815 series of mixed-signal power management ICs. It is designed to replace discrete solutions by integrating multiple power stages into one chip. The series targets applications needing high density and efficiency. Other variants in the family may offer different pin counts or integrated features while maintaining similar control architectures.

DC DC Switching Controllers Replacement Considerations

The LTC7815HUHF#TRPBF serves as a functional equivalent with identical electrical characteristics but differs in packaging format. Verify pin-to-pin compatibility and thermal performance similarities before substitution. Ensure the replacement variant meets the same environmental operating temperature ranges.
