LTC3886EUKG#PBF

DC DC Switching Controllers Overview

The LTC3886EUKG#PBF is a dual PolyPhase DC/DC synchronous step-down switching regulator controller featuring an I2C-based PMBus compliant serial interface. It employs a constant-frequency, current-mode architecture with high voltage input and output capabilities. The device supports programmable loop compensation and DCR detection for accurate load regulation. Input voltage ranges from 4.5V to 60V, while outputs support up to 13.8V. Switching frequency is configurable between 100kHz and 750kHz. It integrates a 16-bit ADC, 12-bit DAC, and internal EEPROM. The component is housed in a 52-pin QFN package measuring 7mm x 8mm.

DC DC Switching Controllers Feature Summary

• Dual-channel PolyPhase control architecture supporting up to six phases per channel for precise current sharing.
• Integrated digital power management via PMBus interface enabling telemetry readback and remote configuration.
• Built-in DCR sensing capability eliminates the need for external sense resistors for load regulation.
• Comprehensive protection features including over-voltage, under-voltage, over-temperature, and over-current monitoring.

DC DC Switching Controllers Applications

• High-density point-of-load (POL) conversion in server and storage systems
• Distributed power architectures requiring multi-phase buck regulation
• Industrial equipment with wide input voltage requirements
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify that the specific suffix #PBF corresponds to the tube packaging variant when sourcing components. Confirm that the EUKG designation matches the required thermal pad and pinout specifications for the target PCB footprint. Ensure compatibility with the intended PMBus implementation as the controller relies on digital communication for configuration and monitoring functions.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring high efficiency across wide load ranges without external current sense resistors. The dual-channel design allows independent regulation of two distinct output rails. Consider the 52-pin QFN package constraints for thermal management and layout complexity. The integrated digital interface simplifies system monitoring but requires appropriate bus pull-up resistors and address configuration.

DC DC Switching Controllers Part Context

This component belongs to the Analog Devices LTC3886 family of dual-channel synchronous buck controllers. It is designed for high-performance power management where digital control and high accuracy are critical. The device complements other PolyPhase controllers by offering integrated analog front-end processing with robust digital oversight capabilities.

DC DC Switching Controllers Replacement Considerations

LTC3886EUKG-1#PBF serves as a direct functional substitute within the same series, maintaining identical electrical characteristics and pinout compatibility.
