LTC3836EUFD#TRPBF

DC DC Switching Controllers Overview

The LTC3836EUFD#TRPBF is a dual-phase, no RSENSE synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.75 V to 4.5 V and supports output voltages from 600 mV to 4.365 V. The device delivers up to 20 A of output current across two outputs. Key electrical parameters include a quiescent current of 6.5 uA, a switch frequency range of 300 kHz to 750 kHz, and a maximum operating temperature of +85 C. It utilizes a QFN-28 package for surface mount installation.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture enables high current delivery without requiring sense resistors
• Integrated synchronization control allows tracking with external clocks or other controllers
• Low quiescent current operation supports efficient power management in standby modes

DC DC Switching Controllers Applications

• Point-of-load regulation for processors and memory in low-voltage systems
• Industrial equipment requiring synchronized multi-phase power distribution
• Telecommunications infrastructure utilizing 3.3 V input rails

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the QFN-28 package dimensions match your PCB footprint requirements. Ensure the input voltage does not exceed 4.5 V during operation. Check for RoHS compliance documentation if required by your manufacturing standards. Validate thermal performance within the specified -40 C to +85 C operating range.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring dual independent outputs from a single controller IC. It is suitable for applications where board space is limited due to the compact QFN-28 form factor. Consider the 2.75 V minimum input voltage constraint against your available supply rails. The no RSENSE feature simplifies layout compared to traditional current-mode controllers. Evaluate the 300 kHz to 750 kHz frequency range against EMI requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC3836 series of dual-phase synchronous buck controllers. It shares the QFN-28 package style with other Analog Devices PMICs like the LT3071EUFD#TRPBF but differs in topology and phase count. Unlike the LTC3838IUHF-1#TRPBF which handles higher voltages, this model is optimized for low-input applications. The #TRPBF suffix distinguishes it from tube-packaged variants like the LTC3836EUFD#PBF.
