LT4363IDE-2#PBF

Overview

The LT4363IDE-2#PBF is a demonstration board for the LT4363-2 high voltage surge stopper. It showcases the component in a 12V, 2A application configuration. The circuit limits inputs of up to 80VDC and 1ms transients of up to 250V to an output of 16.3V. The MOSFET is protected against output overloads via current limiting. Sustained overvoltage or overcurrent conditions trigger a timer delay before shutdown. The LT4363-2 variant automatically retries after a cool-down delay.

Feature Summary

• Demonstrates high voltage surge stopping with automatic retry functionality
• Provides current limiting protection for output MOSFETs against overloads
• Configurable for 28V systems by removing specific zero-ohm jumpers

Applications

• Evaluation of 12V system surge protection circuits
• Testing high voltage transient immunity up to 250V
• Assessment of automatic retry behavior under sustained fault conditions

Procurement Notes

Verify that the LT4363IDE-2#PBF designation refers specifically to the Analog Devices demonstration kit rather than the standalone IC. Confirm compatibility with required evaluation software and design files available from the manufacturer. Ensure the demo board meets specific testing requirements for 12V applications with 2A load capabilities.

Selection Notes

Select this board when evaluating the LT4363-2 device's performance in standard 12V architectures. It is suitable for verifying automatic retry mechanisms and transient suppression characteristics. Consider alternative demo boards if 28V system configurations are required, as jumper modifications may be necessary for different voltage levels.

Part Context

This part belongs to the LT4363 series of high voltage surge stoppers manufactured by Analog Devices. The IDE suffix indicates it is an evaluation/demo board version designed to showcase the LT4363-2 chip's capabilities. It serves as a reference design platform for engineers developing robust power input protection schemes.

Replacement Considerations

For functional replacement of the underlying IC, consider the LT4363CDE-2#PBF or LT4363IS-2#PBF depending on package requirements. Other demo boards such as DC1935A-A exist for the LT4363-1 variant but lack the automatic retry feature.
