LTC3884IRHE#WTRPBF

DC DC Switching Controllers Overview

The LTC3884IRHE-1#PBF is a dual-output polyphase buck controller from Analog Devices, designed for high-current applications. It operates with an input voltage range of 4.5 V to 38 V and supports output voltages from 500 mV to 5.5 V. The device delivers up to 30 A per channel and features a switchable frequency between 200 kHz and 1 MHz. Packaged in a GQFN-48 format, it functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Integrates two independent synchronous buck channels for parallel operation
• Supports digital power management via I2C and PMBus interfaces
• Features sub-milliohm current sensing for precise load regulation

DC DC Switching Controllers Applications

• High-density server and workstation power distribution
• Telecommunications base station point-of-load conversion
• Industrial equipment requiring multi-phase power delivery

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official documentation, as variations such as #PBF indicate tube packaging while other suffixes may denote tape and reel formats. Confirm that the requested part number matches the exact electrical specifications and package type required for your design, ensuring compatibility with existing supply chains and component availability.

DC DC Switching Controllers Selection Notes

Select this controller when designing systems requiring dual independent outputs or synchronized polyphase operation for reduced ripple. It is suitable for applications needing digital control capabilities through standard communication protocols. Ensure the external components support the selected switching frequency and current requirements to maintain stability and efficiency across the operating temperature range.

DC DC Switching Controllers Part Context

This component belongs to the LTC3884 series of polyphase DC/DC controllers. It is distinct from single-channel variants like the LTC3883 and higher-current models such as the LTC3886. The series is characterized by its ability to drive multiple phases efficiently while maintaining tight voltage regulation and fast transient response times for demanding load conditions.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3884IUH-1#WPBF for alternative packaging options. For lower current requirements, the LTC3883 series may serve as a functional replacement. Higher current needs might require the LTC3886 series. Always verify pinout compatibility and thermal performance before swapping components.
