LT8613IUDE#PBF

Overview

The LT8613IUDE#PBF is a synchronous step-down DC/DC converter from Analog Devices, featuring Silent Switcher 2 architecture. It supports an input voltage range of 3.4V to 65V and delivers up to 8A output current. The device integrates internal bypass capacitors to minimize EMI emissions without layout sensitivity. Key electrical parameters include a 40ns minimum on-time, Burst Mode operation for ultralow quiescent current (2.5μA at 12VIN), and high efficiency up to 95% at 1MHz switching frequency. It operates within a temperature range of -40°C to +125°C.

Feature Summary

Silent Switcher 2 architecture with integrated bypass capacitors for minimized radiated EMI
High-efficiency synchronous buck regulation with fast transient response
Ultralow standby current consumption via Burst Mode operation
Wide input voltage range supporting diverse power supply applications

Applications

Industrial automation controllers
Telecommunications infrastructure equipment
Automotive electronics systems
Point-of-load conversion modules

Procurement Notes

Verify the complete part number including suffixes such as #PBF for lead-free compliance and package type. Confirm that the specific variant matches your required thermal performance and regulatory standards. Cross-reference the manufacturer's official documentation to ensure compatibility with your system design requirements before procurement.

Selection Notes

Select this component when high input voltages up to 65V are required alongside significant current delivery. The integrated EMI suppression simplifies PCB layout compared to discrete solutions. Consider external compensation variants if precise loop control or current sharing between parallel units is necessary for the target application.

Part Context

This part belongs to the LT861x family of high-voltage synchronous step-down converters. It shares architectural similarities with the LT8645S and LT8646S models, utilizing second-generation Silent Switcher technology. The family focuses on reducing electromagnetic interference while maintaining high efficiency in compact form factors suitable for space-constrained designs.
