LTC3784IGN#TRPBF

DC DC Switching Controllers Overview

The LTC3784IGN#TRPBF is a synchronous step-up (boost) DC/DC switching controller from Analog Devices Inc., designed for high-efficiency power conversion. It operates with an input voltage range of 2.3V to 60V and supports output voltages from 1.2V to 60V. The device features a PolyPhase architecture, allowing for multi-phase operation to distribute thermal load and reduce input/output ripple. Key electrical parameters include a switch frequency range of 105kHz to 760kHz, a maximum duty cycle of 96%, and a quiescent current of 28µA. It provides two independent outputs and is housed in a 28-SSOP package.

DC DC Switching Controllers Feature Summary

• PolyPhase synchronous boost control architecture for enhanced current sharing and thermal management
• Wide input voltage capability supporting direct battery connection or bus distribution
• Integrated soft-start, current limit, enable, and power good monitoring functions
• Adjustable switching frequency allows optimization for size and efficiency trade-offs

DC DC Switching Controllers Applications

• Industrial point-of-load regulation
• Battery-powered equipment step-up conversion
• Telecommunications power systems
• Automotive electronics power management

DC DC Switching Controllers Procurement Notes

Verify the suffix IGN indicates the SSOP-28 package variant distinct from the IUFD QFN version. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure the ordering part number matches the required tape and reel quantity specifications for automated assembly processes.

DC DC Switching Controllers Selection Notes

Select this component when wide input voltage ranges up to 60V are required alongside multi-phase scalability. Compare against single-phase alternatives if thermal density permits. Validate that the 28-SSOP footprint aligns with PCB layout constraints compared to the smaller QFN options available in the same family.

DC DC Switching Controllers Part Context

This controller belongs to the PolyPhase series, emphasizing scalable multiphase designs for high-current applications. It complements other Analog Devices PMICs by offering robust boost topology control without integrated power switches, requiring external MOSFET selection based on current and voltage ratings.

DC DC Switching Controllers Replacement Considerations

LTC3784EGN#PBF offers identical functionality in a tube-packaged SSOP-28 format. For QFN packaging requirements, the LTC3784IUFD#PBF serves as the pin-compatible alternative within the same electrical specification envelope.
