LTC3829IFE#PBF

DC DC Switching Controllers Overview

The LTC3829IFE#PBF is a synchronous step-down switching controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5V to 38V and supports output voltages from 600mV to 5V. The device features a fixed switching frequency of 770kHz and can drive up to 90A of output current. It utilizes a TSSOP-38 package and functions within a temperature range of -40°C to +125°C. The controller includes soft start, tracking, and power good signals.

DC DC Switching Controllers Feature Summary

• Supports high-current single-output buck conversion with integrated synchronous rectification control.
• Enables precise voltage regulation through dedicated tracking and soft-start capabilities.
• Operates at a fixed high switching frequency for optimized component size and transient response.

DC DC Switching Controllers Applications

• Point-of-load power distribution in server infrastructure
• High-density computing modules requiring efficient DC/DC conversion
• Industrial equipment power management systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm that the TSSOP-38 package matches your PCB footprint requirements. Ensure the 4.5V to 38V input range aligns with your system's supply rails. Cross-reference the 90A current capability with your thermal design limits. Validate that the 770kHz frequency does not conflict with electromagnetic interference constraints in your application environment.

DC DC Switching Controllers Selection Notes

Select this controller when a single high-current output is required from a wide input voltage range. It is suitable for applications needing fast transient response due to the 770kHz switching frequency. Consider the TSSOP-38 package for surface-mount assembly. Evaluate thermal dissipation needs given the 90A potential output. Compare against other PolyPhase controllers if multi-phase interleaving is necessary for higher current demands.

DC DC Switching Controllers Part Context

This component belongs to the LTC3829 series of synchronous buck controllers from Analog Devices. It is part of the broader PolyPhase family designed for high-performance power management. The device complements other regulators like the LTC3829EUHF which offers a QFN package option. It serves as a core control element for converting higher bus voltages to lower processor or memory rail voltages efficiently.

DC DC Switching Controllers Replacement Considerations

The LTC3829EUHF#PBF is a confirmed substitute offering identical electrical specifications but housed in a 38-QFN package instead of TSSOP-38. Verify pin-to-pin compatibility and thermal pad connections when substituting. No other direct functional replacements are documented in the provided data.
