LT8613EUDE#PBF

Overview

The LT8613EUDE#PBF is a synchronous step-down Silent Switcher 2 regulator from Analog Devices. It operates with an input voltage range of 3.4V to 65V and delivers up to 8A output current. The device integrates second-generation Silent Switcher architecture to minimize EMI emissions without layout sensitivity, utilizing internal bypass capacitors. Key electrical parameters include a maximum switching frequency of 2MHz, a minimum on-time of 40ns, and Burst Mode operation for ultralow quiescent current. It features external compensation options and is housed in a thermally enhanced 28-lead (4mm x 5mm) DFN package.

Feature Summary

• Integrates second-generation Silent Switcher architecture to minimize radiated EMI emissions across any PCB layout
• Features internal bypass capacitors that optimize fast current loops and eliminate layout sensitivity
• Supports high efficiency at high switching frequencies with peak current mode control
• Includes Burst Mode operation for ultralow standby current consumption

Applications

• Industrial systems requiring wide input voltage ranges
• Automotive electronics compatible with 24V and 48V architectures
• Point-of-load regulation for distributed power supplies
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix EUDE against official Analog Devices documentation to confirm pinout and thermal pad configuration. Confirm RoHS compliance status through manufacturer datasheets or environmental files. Cross-reference ordering part numbers with authorized distributors to ensure authenticity. Check for recent product change notifications regarding package or material updates before finalizing procurement.

Selection Notes

Select this component when designing systems requiring high efficiency at switching frequencies up to 2MHz. The integrated Silent Switcher technology is suitable for applications where EMI reduction is critical without complex filtering. Ensure the design accommodates the 65V maximum input voltage and utilizes external compensation if fast transient response or current sharing is required.

Part Context

This part belongs to the LT861x family of Silent Switcher 2 regulators. These devices are designed to replace traditional buck converters in space-constrained applications. The family shares common architectural features including internal bypass capacitors and high-frequency operation capabilities. This specific model offers a balance of high current capability and wide input voltage flexibility.
