LTC3884IRHE#WPBF

DC DC Switching Controllers Overview

The LTC3884IRHE#WPBF is a dual-output synchronous step-down switching controller from Analog Devices, designed for high-density power applications. It operates with an input voltage range of 2.7V to 15V and supports output voltages down to 0.6V. The device integrates two independent buck channels capable of delivering up to 30A per phase when paralleled. It features a programmable switching frequency from 200kHz to 1MHz and includes sub-milliohm current sensing for precise load regulation. The controller offers comprehensive protection features including thermal shutdown and overcurrent protection, housed in a 48-lead GQFN package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #WPBF indicates tube packaging versus other variants. Confirm the IRHE designation corresponds to the industrial temperature range and GQFN-48 package. Ensure compatibility with existing PCB footprints and thermal management designs before procurement. Cross-reference with official Analog Devices documentation for any recent product change notifications affecting this part number.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated outputs are required from a single controller. Consider the 30A per phase capability for high-load applications. Evaluate the need for digital control interfaces if system monitoring is critical. Compare against single-channel controllers if only one output is necessary to optimize cost and board space.

DC DC Switching Controllers Part Context

This part belongs to the LTC3884 family of PolyPhase buck controllers. It is designed to work with external MOSFETs to create efficient DC/DC converters. The series is known for high efficiency and compact solution size in demanding power environments.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-to-pin replacements within the LTC388x family such as the LTC3883 or LTC3885 depending on channel count requirements. Verify that alternative parts support the same input voltage range and current capabilities.
