Other Parts Discussed in Thread: TPS50601A-SP, UC1843A-SP

Hi,

Microsemi has strong FPGA products in space grade temperature. Our FPGA has the remote sensing pins for Core voltage and GND. We are looking for a switching regulator with remote sensing feature with High reliability. The Regulator must be sustained in space qualification tests.

If you any parts, please share to us. Once we have tested with our FPGA, it will be suggested to space vendor to use the regulator.

Hey Srinivasrao,

Unfortunately we don't have a differential sensing feature on any of our space grade switching converters for output voltage.
Some of them allow for differential sensing of the current sense pin, but not the output voltage.

Thanks,
Daniel

Hi Daniel,

Please suggest the space grade part with high reliability and not required to have the remote sensing feature. we will use some layout techniques to avoid the IR drop.

Hey Srinivasarao,

Could you provide me with input/output voltage and output current requirements?

That will allow me to give the best recommendation.

Thanks,

Daniel

Hi,

Output Voltage is 1.2V,, input voltage is depends on customer.

Output Voltage is 1.2V and current is 5A,
Input values depends on customer application. assume like 12V to 3.3V range.

Hey Sreenivasarao,

For applications with Vin <= 7 V I suggest the TPS50601A-SP

For applications with Vin > 7 V I suggest the UC1843A-SP.

If you are unable to use two different ones, the UC1843A-SP will likey have to work for the application.

Thanks,

Daniel
