LTC7813HUH#TRPBF

DC DC Switching Controllers Overview

The LTC7813HUH#TRPBF is a high-performance synchronous Boost+Buck DC/DC switching regulator controller manufactured by Analog Devices Inc. It features an input voltage range of 4.5V to 60V and supports a switching frequency from 850kHz up to 2.25MHz. The device operates within a junction temperature range of -40°C to +150°C and is housed in a 32-pin QFN EP package. It includes independent step-up and step-down controllers capable of regulating two separate outputs or functioning as a cascaded regulator.

DC DC Switching Controllers Feature Summary

• Supports independent regulation of two separate outputs or cascaded operation for wide input-to-output voltage ratios
• Drives all N-channel power MOSFET stages for high efficiency
• Features low quiescent current operation suitable for battery-powered applications

DC DC Switching Controllers Applications

• Cascaded boost+buck regulators with wide input ranges
• Systems requiring independent dual output regulation
• Automotive power management systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the HUH variant meets the required high-temperature operating specifications. Ensure compatibility with the 32-pin QFN EP footprint during PCB layout. Check for AEC-Q100 automotive qualification status if deploying in vehicle environments. Validate supply chain availability through authorized Analog Devices distributors.

DC DC Switching Controllers Selection Notes

Select this component when designing circuits that require handling input voltages significantly higher or lower than the desired output voltage. The cascaded topology allows for efficient power conversion across wide dynamic ranges. Consider the 32-pin QFN EP package for thermal performance and space constraints. Verify that the external MOSFET selection aligns with the controller's drive capabilities and the target switching frequency.

DC DC Switching Controllers Part Context

This part belongs to the LTC7813 family of synchronous boost+buck controllers. It shares functional similarities with other devices in the series but is distinguished by its specific pinout, thermal pad configuration, and automotive-grade temperature rating. The HUH suffix denotes the specific package and temperature grade variant within the broader product line.

DC DC Switching Controllers Replacement Considerations

LTC7813IUH#TRPBF is a public confirmed substitute offering similar functionality in a tube package rather than tape and reel.
