LTC3880IUJ-1#TRPBF

DC DC Switching Controllers Overview

The LTC3880IUJ-1#TRPBF is a dual-channel PolyPhase DC/DC synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It features an I2C-based PMBus compliant serial interface for digital power system management. The device supports an input voltage range of 4.5 V to 24 V and delivers up to 30 A per output channel. It operates with a fixed switching frequency of 1 MHz and provides an adjustable output voltage range from 500 mV to 5.4 V. The component is housed in a 40-lead QFN package rated for operation between -40°C and +125°C.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture enabling independent or synchronized multi-phase buck regulation
• Integrated I2C-compatible PMBus interface for comprehensive digital control and monitoring
• Supports high-frequency operation at 1 MHz for compact passive component sizing

DC DC Switching Controllers Applications

• High-density server and storage power distribution networks
• Telecommunications base station point-of-load regulation
• Industrial equipment requiring precise digital power management

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the -I temperature grade matches environmental requirements. Ensure compatibility with existing PMBus software stacks before integration. Check current supply status as availability may vary by region.

DC DC Switching Controllers Selection Notes

Select this model for applications requiring two isolated or non-isolated outputs with digital oversight. Compare against the standard LTC3880 if the -1 variant's specific pinout or internal configuration is necessary. Consider the QFN-40 thermal performance for high-current designs.

DC DC Switching Controllers Part Context

This component belongs to the LTC3880 family of PolyPhase controllers, designed for high-efficiency power conversion. It complements evaluation boards such as the DC1709A for design verification. The series emphasizes digital programmability alongside robust analog control loops for stable transient response.

DC DC Switching Controllers Replacement Considerations

The LTC3880EUJ-1#TRPBF serves as a direct electrical substitute within the same package and specification profile. Verify that the E-grade temperature rating aligns with the operational environment before substitution.
