LTC3827EG-1#PBF

DC DC Switching Controllers Overview

The LTC3827EG-1#PBF is a low quiescent current, dual-phase synchronous step-down controller manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 400 kHz and supports output voltages ranging from 800 mV to 10 V. The device is designed to drive external N-channel power MOSFETs in a two-phase configuration, delivering up to 25 A per phase. It features an SSOP-28 package and functions within an operating temperature range of -40°C to +85°C. The controller draws only 80 µA of supply current during operation.

DC DC Switching Controllers Feature Summary

• Dual-phase synchronous buck control architecture for high-current applications
• Low quiescent current consumption of 80 µA for improved efficiency
• Integrated soft-start and tracking capabilities for controlled power sequencing

DC DC Switching Controllers Applications

• High-density point-of-load (POL) voltage regulation
• Industrial equipment power distribution systems
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel or tube packaging as defined by Analog Devices standards. Confirm RoHS compliance status through official documentation prior to integration. Ensure the SSOP-28 footprint matches the target PCB layout requirements. Validate that the 400 kHz fixed frequency aligns with electromagnetic interference constraints in the final system design.

DC DC Switching Controllers Selection Notes

Select this component when a stable dual-phase solution with minimal standby power is required. The fixed 400 kHz frequency simplifies filter design compared to adjustable frequency alternatives. Consider the 25 A per phase capability against total load requirements. The SSOP-28 package offers a balance between thermal performance and board space constraints for medium-density designs.

DC DC Switching Controllers Part Context

This part belongs to the LTC3827 family of PolyPhase controllers, designed for efficient multi-phase step-down conversion. The EG-1 variant specifies the commercial temperature grade and SSOP-28 package type. It complements other devices in the series like the LTC3827EUH which utilizes a QFN package for different thermal profiles.

DC DC Switching Controllers Replacement Considerations

LTC3827EG-1#TRPBF serves as the tape and reel version of the same functional device. Direct substitution requires verifying that the packaging format change does not impact automated assembly processes. No alternative pin-compatible parts are confirmed in the provided data.
