LTC3883EUH-1#PBF

DC DC Switching Controllers Overview

The LTC3883EUH-1#PBF is a single-phase buck DC/DC controller from Analog Devices, designed for high-performance power management applications. It operates with an input voltage range of 4.5V to 24V and supports output voltages from 500mV to 5.4V. The device delivers up to 30A of output current and features a programmable switching frequency between 250kHz and 1MHz. It utilizes a 32-lead QFN package and is qualified under AEC-Q100 standards for automotive reliability. The operational temperature range extends from -40°C to +105°C.

DC DC Switching Controllers Feature Summary

• Integrated digital power system management via I²C and PMBus interfaces for precise configuration and monitoring
• Automotive-grade qualification ensuring reliability in demanding environments
• Supports clock synchronization and phase control for multi-phase expansion

DC DC Switching Controllers Applications

• Automotive infotainment and telematics systems
• Industrial equipment power distribution
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm that the EUH variant meets the required -40°C to +105°C operating temperature range for your application environment. Ensure compatibility with AEC-Q100 requirements if deploying in automotive contexts. Cross-reference the datasheet for pinout consistency with existing PCB layouts.

DC DC Switching Controllers Selection Notes

Select this component when digital control via PMBus or I²C is required for a single-phase buck converter. It is suitable for designs needing AEC-Q100 compliance without the extended 125°C junction temperature of the IUH variants. Consider the 30A current capability and 24V maximum input voltage against load requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC3883 family of PolyPhase controllers. It shares core architecture with the LTC3883IUH series but differs in thermal rating and automotive qualification. The EUH designation specifically denotes the industrial temperature grade and AEC-Q100 certification, distinguishing it from standard commercial options.

DC DC Switching Controllers Replacement Considerations

The LTC3883EUH-1#WPBF serves as the tape-and-reel equivalent for automated assembly. For non-automotive applications requiring higher thermal performance, the LTC3883IUH-1#PBF offers a 125°C junction temperature rating.
