LTC7820IUFD#PBF

DC DC Switching Controllers Overview

The LTC7820IUFD#PBF is a hybrid step-down synchronous controller manufactured by Analog Devices Inc. It operates within an input voltage range of 36V to 60V and supports up to 10A output current. The device utilizes a 2:1 step-down charge pump architecture with a fixed switching frequency of 200kHz. It is housed in a QFN-28 package (4x5mm) and functions as a non-isolated DC/DC converter. The component is rated for operation between -40°C and +125°C.

DC DC Switching Controllers Feature Summary

• Integrates a 2:1 step-down charge pump topology for high-efficiency power conversion
• Supports dual-phase synchronous buck control for enhanced current handling
• Features adjustable dead-time control and floating ground capabilities

DC DC Switching Controllers Applications

• Industrial power distribution systems
• Automotive electronics requiring robust voltage regulation
• Avionics power management units

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance before procurement. Confirm availability status, as supply may be limited or subject to factory special orders. Ensure the QFN-28 package dimensions align with PCB footprint requirements. Validate that the 36V to 60V input range matches the system design specifications.

DC DC Switching Controllers Selection Notes

Select this component when a stable 2:1 step-down ratio is required from a 36V to 60V source. It is suitable for applications demanding high efficiency without magnetic components in the primary stage. Consider the thermal performance of the QFN-28 package for heat dissipation needs. Verify compatibility with external synchronous MOSFETs for the 10A load requirement.

DC DC Switching Controllers Part Context

This part belongs to the LTC7820 series of hybrid step-down controllers. It combines switched-capacitor technology with traditional synchronous buck control. The series is designed for applications where size and efficiency are critical constraints. It serves as a specialized solution for mid-voltage input ranges common in industrial and automotive sectors.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other Analog Devices hybrid controllers such as the LTC7820EUFD#PBF. Cross-reference pinout and thermal characteristics carefully. Verify that alternative parts support the same 36V to 60V input range and 200kHz switching frequency.
