LTC3736EUF-2#PBF

DC DC Switching Controllers Overview

The LTC3736EUF-2#PBF is a dual 2-phase synchronous step-down switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and provides two independent outputs adjustable from 600mV to 9.8V. The device supports output currents up to 5A per phase with a fixed switching frequency of 750kHz. It features a micropower shutdown mode drawing only 9µA quiescent current and includes internal soft-start, power good monitoring, and overvoltage protection. Packaged in a compact 4mm x 4mm 24-pin QFN.

DC DC Switching Controllers Feature Summary

• Eliminates the need for current sense resistors through integrated no RSENSE technology
• Provides out-of-phase controller operation to reduce required input capacitance
• Includes a tracking function allowing synchronized output voltage sequencing

DC DC Switching Controllers Applications

• Point-of-load regulation for high-performance processors
• Industrial equipment requiring efficient dual-rail power distribution
• Telecommunications infrastructure power systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before integration. Confirm the UF package designation matches your PCB footprint requirements. Ensure the DC922A development kit is available if hardware validation is necessary during the design phase.

DC DC Switching Controllers Selection Notes

Select this component when designing dual-output buck converters that require precise synchronization without external sensing components. It is suitable for applications demanding low input voltage ranges and high efficiency under varying load conditions. Consider the 24-QFN package constraints for thermal management and layout density.

DC DC Switching Controllers Part Context

This part belongs to the LTC3736 family of dual 2-phase controllers. It shares architectural similarities with the LTC3736EUF-1#TRPBF but differs in pinout configuration and specific feature enablement. The series is designed for high-density power conversion solutions requiring minimal external component counts.

DC DC Switching Controllers Replacement Considerations

The LTC3736EUF-1#TRPBF serves as a functional alternative within the same family, though pin compatibility must be verified against the specific circuit design requirements.
