LTC3834EDHC-1#PBF

DC DC Switching Controllers Overview

The LTC3834EDHC-1#PBF is a synchronous step-down controller from Analog Devices, designed for high-efficiency power conversion. It operates with an input voltage range of 4 V to 36 V and supports output voltages from 800 mV to 10 V. The device delivers up to 25 A of output current while maintaining a low quiescent current of 30 uA. It features a fixed switching frequency of 400 kHz and offers precise load regulation of 0.1%. The component is housed in a compact 16-lead DFN package (5mm x 3mm) with an exposed pad, suitable for surface mount applications across a temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology for efficient step-down conversion
• Low quiescent current operation for improved efficiency
• Compact 16-lead DFN package design

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial systems
• Power distribution networks for embedded electronics
• Telecommunications equipment power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence. Confirm the 16-lead DFN package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet for thermal performance data under expected load conditions.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 400 kHz switching frequency is required. It is suitable for designs needing 25 A output capability within a 4 V to 36 V input window. Consider the 16-lead DFN package for space-constrained layouts. Verify that the 800 mV minimum output voltage aligns with your target rail requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC3834 family of synchronous DC/DC controllers. It shares functional similarities with other members like the LTC3834EGN-1#PBF but differs in package type. The EDHC variant specifically utilizes a 16-lead DFN form factor, distinguishing it from SSOP or QFN options in the broader series.

DC DC Switching Controllers Replacement Considerations

The LTC3834EGN-1#PBF serves as a pin-compatible alternative using an SSOP-16 package. Verify thermal dissipation differences between the DFN and SSOP packages during substitution.
