LTC3827EUH#PBF

DC DC Switching Controllers Overview

The LTC3827EUH#PBF is a dual-phase synchronous step-down DC/DC controller from Analog Devices, designed for high-efficiency power conversion. It operates with a supply voltage range of 4V to 36V and supports switching frequencies between 250kHz and 530kHz. The device features a maximum duty cycle of 99.4% and includes two output channels. Packaged in a 32-WFQFN (5x5) surface-mount format with an exposed pad, it functions within a temperature range of -40°C to 85°C. Key control characteristics include enable functionality, phase control, power good indication, soft start, and tracking capabilities.

DC DC Switching Controllers Feature Summary

• Dual-channel architecture supporting independent or synchronized operation for reduced input ripple
• Integrated OPTI-LOOP compensation for optimized transient response across varying output capacitance
• Precision internal reference with dedicated TRACK/SS pins for controlled startup sequencing

DC DC Switching Controllers Applications

• Distributed power systems requiring multi-phase buck regulation
• Battery-operated digital devices needing extended run time via low quiescent current
• Automotive always-on systems utilizing wide input voltage ranges

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free RoHS compliance when ordering. Confirm the package type matches the 32-QFN footprint requirements for your PCB layout. Ensure the operating temperature range aligns with your system's environmental specifications. Cross-reference the datasheet revision to confirm feature consistency. Validate that the supplier provides official documentation for quality assurance.

DC DC Switching Controllers Selection Notes

Select this component when a dual-phase solution is required to minimize input capacitor size and reduce noise. Consider the 4V to 36V input range compatibility with your power source. Evaluate the need for external synchronization if multiple converters are present. Assess the thermal performance requirements given the QFN package. Compare against single-phase alternatives if lower current is sufficient.

DC DC Switching Controllers Part Context

This part belongs to the PolyPhase series of switching controllers, designed for high-density power applications. It complements other models like the LTC3827EG-1#PBF by offering a different package option while maintaining similar electrical performance. The EUH designation specifies the 32-WFQFN package variant, distinguishing it from tube-packaged versions.

DC DC Switching Controllers Replacement Considerations

LTC3827EG-1#PBF offers identical electrical specifications but utilizes an SSOP-28 package instead of the QFN form factor.
