LTC3856EUH#TRPBF

DC DC Switching Controllers Overview

The LTC3856EUH#TRPBF is a single-output synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4.5 V to 38 V and supports output voltages from 600 mV to 5 V with a maximum output current capability of 60 A. The device features a programmable switching frequency adjustable between 250 kHz and 770 kHz. It utilizes a QFN-32 package, supports surface mount installation, and functions reliably across an operating temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Integrates a differential amplifier for true remote sensing of regulated supply terminals to ensure high accuracy in high-current applications.
• Supports phase-lockable fixed frequency architecture allowing expansion for multi-phase systems requiring high output currents.

DC DC Switching Controllers Applications

• High-density point-of-load power supplies
• Industrial equipment requiring precise voltage regulation
• Telecommunications infrastructure power distribution

DC DC Switching Controllers Procurement Notes

Verify the specific suffix EUH against official datasheets to confirm the package type and temperature grade match design requirements. Confirm availability status as distribution channels may indicate limited stock or special order constraints. Ensure compatibility with external MOSFET selection for the specified 60 A current rating.

DC DC Switching Controllers Selection Notes

Select this component when designing single-output buck converters requiring up to 60 A. The integrated differential amplifier simplifies layout for remote sensing compared to standard controllers. Verify that the chosen external components support the 4.5 V to 38 V input range and the desired switching frequency setting.

DC DC Switching Controllers Part Context

This part belongs to the LTC3856 series of PolyPhase controllers designed for sub-milliohm DCR sensing. It is distinct from other models like the LTC3859 which offers multiple outputs or the LTC3827 which supports two phases. The EUH suffix denotes the specific QFN-32 package variant.

DC DC Switching Controllers Replacement Considerations

LTC3856IUH#PBF is a pin-compatible alternative within the same family offering similar electrical characteristics but potentially different packaging or temperature specifications.
