LTC3827EG-1#TRPBF

DC DC Switching Controllers Overview

The LTC3827EG-1#TRPBF is a low quiescent current, dual-phase synchronous step-down controller manufactured by Analog Devices. It operates with a fixed switching frequency of 400 kHz and supports output voltages ranging from 800 mV to 10 V. The device delivers up to 25 A of output current per phase. It functions within an input voltage range of 4 V to 36 V and maintains a typical operating supply current of 80 uA. The component is housed in a 28-pin SSOP package and is rated for operation between -40°C and +85°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official documentation to confirm packaging format. The #TRPBF designation indicates tape and reel packaging, which differs from tube variants. Confirm RoHS compliance status directly with the manufacturer datasheet. Ensure the order matches the exact pinout and thermal requirements for the SSOP-28 package.

DC DC Switching Controllers Selection Notes

Select this controller when dual-phase high-current delivery is required with minimal standby power consumption. The fixed 400 kHz frequency allows for optimized passive component selection. Verify that the application input voltage remains within the 4 V to 36 V operational window. Consider the SSOP-28 package constraints for PCB layout and thermal dissipation relative to the 25 A per phase capability.

DC DC Switching Controllers Part Context

This component belongs to the LTC3827 family of PolyPhase controllers designed for efficient power conversion. It serves as a core management IC for multi-phase buck converters, coordinating gate drive signals to external MOSFETs. The EG-1 variant specifies the commercial temperature grade and standard packaging options available through authorized distribution channels.

DC DC Switching Controllers Replacement Considerations

Consult official substitution guides for equivalent dual-phase controllers. Verify pin compatibility and electrical specifications before replacing.
