LT8342RV#PBF

Overview

The LT8342RV#PBF is a low input current, synchronous step-up DC/DC converter featuring Silent Switcher architecture. It supports an input voltage range of 6V to 20V and delivers up to 7A output current with a maximum output voltage of 40V. The device operates at switching frequencies up to 2MHz and includes optional spread spectrum frequency modulation for EMI reduction. It integrates input disconnect and PassThru functionality within a compact 24-lead LQFN package.

Feature Summary

Silent Switcher architecture minimizes radiated electromagnetic interference without external snubbers
Integrated input disconnect prevents reverse current flow from output to input
PassThru mode allows direct connection of input source to load when input exceeds output

Applications

Industrial systems requiring low noise power conversion
Battery-powered equipment needing efficient step-up regulation
Automotive electronics with strict EMI constraints

Procurement Notes

Verify the specific suffix RV indicates the 24-lead LQFN (4x4) package variant. Confirm RoHS compliance status through official Analog Devices documentation. Ensure compatibility with required thermal management solutions for high-current operation. Check for any recent product change notices affecting pinout or electrical characteristics.

Selection Notes

Select this component for applications requiring high efficiency in space-constrained designs. The Silent Switcher technology reduces the need for complex filtering components. Consider the 2MHz switching frequency for smaller passive component sizes compared to lower frequency alternatives. Evaluate thermal performance requirements given the 7A capability in a small footprint.

Part Context

This part belongs to the LT8342 family of synchronous step-up converters from Analog Devices. It shares architectural similarities with other Silent Switcher devices but offers specific current and voltage ratings tailored for industrial and automotive use cases. The RV suffix denotes the specific package and temperature grade configuration.
