LT83205RUDB#TRPBF

Overview

The LT83205RUDB#TRPBF is a synchronous step-down switching regulator from Analog Devices, featuring the Silent Switcher 3 architecture. It supports an input voltage range of 2.8 V to 18 V and delivers up to 5 A output current. The device integrates high-side and low-side power switches within a compact LFCSP-15 package. Key electrical parameters include a maximum switching frequency of 6 MHz and a quiescent current of 100 uA. It operates across a temperature range of -40°C to +150°C.

Feature Summary

Silent Switcher 3 topology for ultra-low radiated electromagnetic interference without external shielding
Integrated synchronous rectification with internal high and low-side power MOSFETs
Ultra-low noise reference design minimizing output ripple and conducted emissions

Applications

Industrial automation control systems
Telecommunications infrastructure power distribution
Medical equipment power supplies
Automotive electronics modules

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request original manufacturer documentation and lot traceability certificates upon order confirmation. Ensure storage conditions comply with moisture sensitivity level requirements specified in the datasheet to maintain solderability and reliability during assembly processes.

Selection Notes

Select this component for applications requiring high efficiency and minimal electromagnetic interference in space-constrained designs. The integrated power stage eliminates the need for external Schottky diodes. Evaluate thermal performance based on PCB copper area and airflow conditions, as the LFCSP-15 package relies on board-level heat dissipation for optimal operation under full load conditions.

Part Context

This part belongs to the LT8320x series of Silent Switcher regulators, designed for high-density power conversion. It shares architectural similarities with the LT83203 but offers higher current capability. The RUDB suffix indicates the specific LFCSP-15 package variant optimized for surface-mount assembly and thermal management in compact electronic assemblies.
