Part Number: UC1843B-SP Hello Guys,
Good day.
Can the UC1843B-SP be use to drive a GAN FET ? If it can, are there GAN parts that are recommended with UC1843B-SP?
Thanks in advance.

Hello Giacomo,
The easiest thing to do would be to divide down the sawtooth from the clock of the UC1843B-SP.
If you look at the EVM for the UC1843B-SP you can see something similar was used for slope compensation.
Its a relatively simple modification…
Part Number: UC1843B-SP Hello,
I am having trouble finding information about radiation hardness, TID , and displacement damage about this part. Is there any info you can provide or direct me to it?
Thanks,

Please tell us what the differences are between the UC1843-SP, UC1843A-SP and UC1843B-SP.
Thank you.

Thanks for your reply.
Should I use only UC1843B-SP for space?
I don't know what's the difference between UC1843, UC1843A, and UC1843B.
Is they are all the same functions?
Why are you suggesting UC1843B-SP?

I want to make a boost converter for low-orbit satellites.
Conditions
1. Input : 30V
2. Output : 150V / 100mA
Can I use this device for it?
Any other…
Hey Vince,
Your implementation is similar to how one would do it on the UC1843B-SP. Note that the RAMP signal generated here needs a capacitor in order to be formed, and SLOPE needs a resistor.
Thanks, Daniel
Hey Vince,
Apologies I only answered 1 question.
That circuit was a rudimentary soft start to add to the UC1843B-SP. Depending on your controller it may not be required.
Thanks, Daniel
