LTC3788IUH#TRPBF

DC DC Switching Controllers Overview

The LTC3788IUH#TRPBF is a dual-phase, dual-output synchronous boost controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5V to 38V and supports switching frequencies between 105kHz and 760kHz. The device features a maximum duty cycle of 96% and utilizes a 32-WFQFN (5x5) package with an exposed pad for surface mount installation. It provides two output stages and includes control characteristics such as current limiting, enable, frequency control, power good indication, and soft start functionality.

DC DC Switching Controllers Feature Summary

• Dual-phase architecture supporting independent dual outputs
• Synchronous rectification for enhanced efficiency
• Integrated control features including soft start and power good monitoring

DC DC Switching Controllers Applications

• DC/DC step-up converter designs requiring dual isolated or non-isolated outputs
• Industrial power management systems
• Automotive electronics applications

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the IUH designation corresponds to the industrial temperature grade (-40°C to +125°C TJ). Ensure compatibility with the 32-QFN footprint during PCB layout verification. Cross-reference the manufacturer's latest datasheet for any assembly or material changes documented in recent PCNs.

DC DC Switching Controllers Selection Notes

Select this component when a single controller is needed to drive two separate boost channels independently. The wide input voltage range accommodates various source conditions up to 38V. The adjustable frequency allows optimization for external component size versus noise performance. Verify that the required output voltage range aligns with the controller's capabilities and that the thermal performance of the QFN package suits the application's power dissipation requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC3788 family of PolyPhase controllers designed for high-efficiency boost applications. It shares functional similarities with other members like the LTC3788EUH but differs in package type and temperature rating. The series is characterized by its ability to manage multiple phases from a single IC, reducing board space compared to using discrete controllers for each phase.

DC DC Switching Controllers Replacement Considerations

LTC3788IUH#PBF offers the same electrical specifications in tube packaging instead of tape and reel.
