LT8364EDE#TRPBF

Overview

The LT8364EDE#TRPBF is a current mode DC/DC converter featuring an integrated 60V, 4A power switch. It operates from an input voltage range of 2.8V to 60V and supports Boost, SEPIC, or Inverting topologies via a unique single feedback pin architecture. Burst Mode operation ensures low quiescent current of 9µA while maintaining output ripple below 15mV. The device includes an external compensation pin for loop optimization across switching frequencies from 300kHz to 2MHz. It utilizes a 12-lead DFN package with exposed pad.

Feature Summary

• Single feedback pin architecture enables flexible configuration for boost, SEPIC, or inverting applications
• Burst Mode operation maintains high efficiency at very low output currents with minimal output ripple
• External compensation pin allows precise optimization of loop bandwidth over wide input and output voltage ranges
• Integrated BIAS pin accepts a second input to supply the INTVCC regulator for increased system efficiency

Applications

• Industrial systems requiring isolated or non-isolated power conversion
• Battery-powered equipment needing extended runtime through ultra-low standby current
• Automotive electronics operating within wide input voltage variations
• Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm temperature grade and packaging details. Ensure compatibility with required thermal management solutions given the DFN-12 package constraints. Confirm availability status as distribution channels may report limited stock or restricted supply conditions. Validate RoHS compliance requirements against project specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require handling high input voltages up to 60V with a compact footprint. The single feedback pin simplifies layout compared to traditional multi-pin feedback networks. Consider the external compensation requirement for stability across varying load conditions. Evaluate the need for Spread Spectrum Frequency Modulation if EMI reduction is critical for the target application environment.

Part Context

This part belongs to the LT8364 family of high-voltage DC/DC converters manufactured by Analog Devices. It shares architectural similarities with other devices in the series but is distinguished by its specific 4A switch rating and 60V breakdown capability. The DEDE suffix indicates the industrial temperature grade and DFN-12 package variant, differentiating it from MSOP or higher voltage switch variants within the broader product line.

Replacement Considerations

LT8364HDE#TRPBF offers similar functionality with potentially different thermal characteristics or temperature ratings.
