LTC3829EFE#PBF

DC DC Switching Controllers Overview

The LTC3829EFE#PBF is a synchronous three-phase, single-output step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5V to 38V and supports switching frequencies from 250kHz to 770kHz. The device delivers up to 90A output current with adjustable output voltages between 600mV and 5V. Packaged in a 38-lead TSSOP (EP) for surface mount installation, it functions across an extended temperature range of -40°C to +125°C TJ. Key control features include cycle-by-cycle current limit, soft start, tracking, and power good indication.

DC DC Switching Controllers Feature Summary

• Supports multiphase operation for high-current delivery using external N-channel MOSFETs
• Integrates programmable frequency synchronization and phase-shift control capabilities
• Provides comprehensive protection including thermal regulation and overcurrent limiting

DC DC Switching Controllers Applications

• High-density server and data center point-of-load power distribution
• Telecommunications infrastructure equipment requiring stable bus conversion
• Industrial automation systems demanding robust power management solutions

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards before ordering. Confirm that the TSSOP-38 package matches your PCB footprint requirements. Ensure the selected switching frequency configuration aligns with your system's electromagnetic interference constraints. Cross-reference the datasheet revision date to confirm compatibility with your design specifications.

DC DC Switching Controllers Selection Notes

Select this component when designing multi-phase buck converters requiring high transient response and efficiency. Consider the 38-pin TSSOP package size against available board space. Evaluate the 250kHz to 770kHz frequency range to balance component size against dynamic performance needs. Verify that the 4.5V minimum input voltage suits your source supply characteristics.

DC DC Switching Controllers Part Context

This part belongs to the PolyPhase family of synchronous controllers designed for high-performance applications. It complements other Analog Devices PMICs by offering scalable current capability through phase multiplication. The device integrates advanced control loops to maintain stability under varying load conditions while minimizing output ripple voltage.

DC DC Switching Controllers Replacement Considerations

Direct replacements may include variants within the same PolyPhase series such as the LTC3829EUHF#PBF which utilizes a QFN package instead of TSSOP. Verify pinout compatibility and thermal pad connections when substituting packages. Check if alternative suffixes offer different temperature grades or packaging formats.
