DC DC Switching Controllers datasheet and documents for LTC3827IUH#PBF

LTC3827IUH#PBF

DC DC Switching Controllers Overview

The LTC3827IUH#PBF is a dual synchronous step-down switching regulator controller from Analog Devices, designed for high-efficiency power delivery. It features a constant frequency current mode architecture with a switchable frequency range of 250kHz to 530kHz. The device supports an input voltage range of 4V to 36V and provides two independent output channels. Each channel can deliver up to 25A of output current, with adjustable output voltages ranging from 800mV to 10V. Operating in the industrial temperature range of -40°C to +85°C, it utilizes a 32-lead QFN package.

DC DC Switching Controllers Feature Summary

Dual-channel architecture enables simultaneous control of two independent synchronous buck converters
OPTI-LOOP compensation optimizes transient response across varying output capacitance and ESR values
Independent TRACK/SS pins allow precise ramping and tracking of output voltages during startup
Current foldback protection limits MOSFET heat dissipation during short-circuit conditions

DC DC Switching Controllers Applications

Distributed DC power systems
Battery operated digital devices
Automotive always-on systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging compliance. Confirm the 'I' grade meets the required -40°C to +85°C operating temperature range for your application environment. Ensure the 32-QFN footprint matches your PCB layout constraints before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated outputs are required from a single controller. The wide input voltage range suits applications powered by 12V, 24V, or 36V buses. Consider the 25A per channel capability for moderate load requirements where thermal management via the exposed pad is feasible.

DC DC Switching Controllers Part Context

This part belongs to the PolyPhase series of power management ICs. It complements other controllers like the LTC3890 by offering a lower input voltage ceiling but maintaining dual-phase synchronization capabilities. It serves as a core component for multi-rail power architectures in compact electronic designs.
