LT8342RV#TRMPBF

Overview

The LT8342RV#TRMPBF is a synchronous step-up DC/DC converter featuring Silent Switcher architecture. It supports an input voltage range of 2.8V to 40V and delivers up to 9A output current. The device offers programmable output voltage up to 36V with low quiescent current. Operating frequencies are selectable, and it includes optional spread spectrum frequency modulation for EMI reduction. The component is housed in a 24-lead LQFN (4x4) package.

Feature Summary

Silent Switcher architecture minimizes electromagnetic interference radiation
Synchronous step-up topology with high efficiency performance
Low quiescent current operation for enhanced power savings
Optional spread spectrum frequency modulation capability

Applications

Industrial control systems
Automotive electronics
Portable instrumentation
Battery-powered equipment

Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging configuration. Confirm the RV grade matches required temperature specifications. Ensure compatibility with existing PCB footprint for the 24-lead LQFN package. Validate supply chain authenticity through authorized channels due to potential limited availability status.

Selection Notes

Select this component when high current boost conversion is required within a compact form factor. The Silent Switcher technology is critical for applications sensitive to radiated emissions without external shielding. Consider the 40V maximum input limit against source voltage peaks. Evaluate thermal management requirements given the 9A continuous current capability in the small package.

Part Context

This part belongs to the LT8342 family of Silent Switcher regulators from Analog Devices. It shares architectural similarities with other members like the LT83402 but differs in topology and current handling. The series emphasizes EMI reduction and high efficiency in power management integrated circuits designed for demanding environments.
