LTC3727EUH-1#TRPBF

DC DC Switching Controllers Overview

The LTC3727EUH-1#TRPBF is a high-efficiency, two-phase synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 36 V and delivers up to 25 A per phase. The device supports output voltages from 800 mV to 14 V and features a fixed switching frequency of 550 kHz. Packaged in a 32-lead QFN (5x5 mm) with an exposed thermal pad, it functions within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Supports dual-phase synchronous buck topology for high current delivery
• Integrated control logic eliminates the need for external sense resistors
• Includes programmable soft-start and tracking capabilities

DC DC Switching Controllers Applications

• DDR and QDR memory termination power supplies
• Central processing unit (CPU) core voltage regulation
• General-purpose point-of-load (POL) conversion

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package marking matches the specific lot code and date code requirements. Ensure storage conditions comply with moisture sensitivity level specifications prior to reflow soldering processes.

DC DC Switching Controllers Selection Notes

Select this controller when designing systems requiring high efficiency at moderate currents without the complexity of current-mode sensing. Evaluate thermal performance based on the QFN package's exposed pad requirements. Verify that the target output voltage range aligns with the specified 800 mV to 14 V limits.

DC DC Switching Controllers Part Context

This component belongs to the LTC3727 family of synchronous buck controllers. It shares architectural similarities with other members like the LTC3728 but differs in pinout and specific feature sets. The EUH suffix denotes the 32-lead QFN package variant, while the TRPBF suffix indicates tape-and-reel packaging with lead-free finish.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3727EG-1#TRPBF for SSOP-28 packaging or the LTC3727EUH-1#TR for non-lead-free variants. Cross-model replacements such as the LTC3728 require schematic adjustments due to different pin configurations.
