LTC3784IGN#PBF

DC DC Switching Controllers Overview

The LTC3784IGN#PBF is a PolyPhase synchronous boost controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.3V to 60V and supports switching frequencies from 105kHz to 760kHz. The device features two outputs and two output stages, housed in a 28-SSOP package. It includes control characteristics such as current limiting, enable, frequency control, power good, and soft start. The maximum duty cycle is 96%, and it functions within a temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Supports multiphase synchronous boost topology for high efficiency
• Integrates dual output drivers for independent regulation
• Includes comprehensive protection and control features like soft start and current limiting

DC DC Switching Controllers Applications

• High power density DC/DC conversion systems
• Industrial power supply designs requiring wide input ranges
• Telecommunications infrastructure power management

DC DC Switching Controllers Procurement Notes

Verify the specific suffix IGN indicates the SSOP-28 package and industrial temperature grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration into production assemblies.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a wide input voltage range up to 60V with synchronous rectification benefits. Ensure the design accommodates the 28-SSOP thermal requirements and that the external inductor selection aligns with the programmable frequency range for optimal performance.

DC DC Switching Controllers Part Context

This part belongs to the LTC3784 series of PolyPhase controllers designed for high-efficiency boost applications. It is distinct from buck or buck-boost variants within the broader Analog Devices PMIC portfolio, specifically optimized for step-up conversion topologies with multi-phase capabilities.

DC DC Switching Controllers Replacement Considerations

LTC3784EGN#PBF shares identical electrical specifications but utilizes an SSOP-28 package instead of QFN, offering pin-compatible alternatives for different board layout constraints.
