LTC7802EUFDM#TRPBF

DC DC Switching Controllers Overview

The LTC7802EUFDM#TRPBF is a dual synchronous step-down switching controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 40V and supports two independent outputs. The device features a low quiescent current of 14µA and allows for adjustable switching frequencies up to 3MHz. It utilizes a 28-lead QFN package designed for surface mount applications.

DC DC Switching Controllers Feature Summary

• Dual output architecture enabling independent regulation for multiple rails
• Ultra-low quiescent current operation for enhanced efficiency in standby modes
• Integrated 3.3V LDO regulator providing stable bias supply
• Synchronous rectification control for high power conversion efficiency

DC DC Switching Controllers Applications

• Industrial equipment requiring multi-rail power distribution
• Telecommunications infrastructure power systems
• Automotive electronics with strict efficiency requirements
• Portable devices utilizing battery-powered architectures

DC DC Switching Controllers Procurement Notes

Verify the specific suffix designation to confirm the inclusion of the integrated 3.3V LDO regulator, as variants without this feature exist within the same family. Ensure the ordering part number matches the required pinout and regulatory compliance status. Confirm package type compatibility during procurement to avoid assembly errors.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated buck converters are required from a single input source. The low IQ specification makes it suitable for battery-operated systems where standby power consumption is critical. Evaluate thermal performance requirements based on the QFN package limitations and expected load currents.

DC DC Switching Controllers Part Context

This controller belongs to the LTC7802 series, which focuses on high-efficiency dual-channel power management. It complements other single-channel controllers like the LTC7801 by offering integrated dual-output capability. The series targets applications demanding compact solutions with minimal external component counts.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC7802EUFDM#PBF for tube packaging or the standard LTC7802EUFDM variant if the internal 3.3V LDO is not required. Verify pin compatibility before replacing with generic dual buck controllers.
