LTC3836EUFD#PBF

DC DC Switching Controllers Overview

The LTC3836EUFD#PBF is a dual-output, two-phase 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 its two channels. Key electrical specifications include a quiescent current of 6.5 uA, a switch frequency adjustable between 300 kHz and 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

• Supports two-phase operation without requiring sense resistors for current monitoring
• Enables synchronization of multiple controllers for phase interleaving
• Integrates low quiescent current architecture for improved efficiency at light loads

DC DC Switching Controllers Applications

• Low voltage point-of-load regulation in computing systems
• Power distribution networks for high-current digital loads
• Industrial equipment requiring efficient buck conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the QFN-28 package dimensions match your PCB footprint design. Ensure the input voltage range aligns with your system's power supply rails. Check for any recent product change notifications that may affect pinout or electrical characteristics.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring high current density from low input voltages. The no-RSENSE feature simplifies layout and reduces cost compared to current-mode controllers. Consider the thermal performance of the QFN-28 package under full load conditions. Verify that the required output voltage range falls within the specified 600 mV to 4.365 V limits.

DC DC Switching Controllers Part Context

This part belongs to the LTC3836 family of dual-phase synchronous step-down controllers. It is designed for applications demanding high efficiency and compact solution size. The device integrates control logic for driving external N-channel MOSFETs. It is distinct from single-phase regulators by offering doubled current capability through phase interleaving.

DC DC Switching Controllers Replacement Considerations

Direct replacements must support dual-phase operation and similar input voltage ranges. Verify compatibility with existing gate drive requirements and feedback network configurations. Ensure thermal management solutions are adequate for equivalent power dissipation levels.
