Differential Remote Sensing Evaluation Board
Jump to Page Section:
Overview
Description
The ISL70002SEHEVAL3Z evaluation board is designed to demonstrate the features of the ISL70002SEH or ISL73002SEH, TID and SEE hardened 22A synchronous buck regulator ICs with integrated MOSFETs intended for space applications.
The ISL70002SEHEVAL3Z is similar to the ISL70002SEHEVAL1Z, but AGND is separated from PGND. This allows remote ground sensing to compensate for voltage loss in the ground path. Ground sensing is an important feature when providing a tightly regulated core voltage for a FPGA or microcontroller.
Features
- Separate VOUT and GND Force and Sense terminals
- Optional 2x2mΩ emulated trace resistance included on board
- 3V to 5.5V input
- Adjustable VOUT from 0.6V to 0.85×VIN

FPGA Reference Design for Rad Hard Applications
Josh Broline discusses the FPGA reference design featuring the ISL70001SEH, ISL70002SEH, and ISL75051SRH radiation hardened products at APEC 2013.
Transcript
Hello from APEC 2013 here in Long Beach, CA. My name is Josh Broline, I'm the product marketing manager for Space and High reliability products group here at Intersil. Here we are demoing Intersil's FPGA reference design, specifically for Xilinx. We have three point-of-load regulators, the ISL70001SEH, which is a 6A regulator. Also, we have the ISL70002SEH, which has an output of 12A. It can also be powered off of a 3.3V or 5V rail. And last, we have the ISL75051, which is a 3A, low dropout regulator. It has superior dropout performance. For example, at 65mV at 1.5A, or about 225mV at 3A. I would actually put this product up specifically next to a commercial type product.
The critical thing to know about these particular products is that we did specific roundup designs to ensure that these products would survive the space and harsh environments. For example, we have single event transient immunity within plus or minus 1%. So if you have a stack up say at plus or minus 5%, that is absolutely critical very tight performance, whether it be at single event transient over radiation and all the different conditions that you would run into. For more information, you can go to the Space and Harsh Environments product page on our website. We have reference designs, application notes. You can get schematics and layout files or you can find more information on these particular products. Also, you can go to the specific product information pages for each individual product.
