Hello!
We are working with LM20333, and we are experimenting some problems with the input voltage range. Basically, our design is exactly the same suggested by the webench of national.com (VOUT=5V) and works fine between 9 to 17.5V of VIN, but the VOUT…
Other Parts Discussed in Thread: PMP7804 , LM20333 , LM21212-1 , LMZ22008 , LMZ22010 , PMP Hello, I'm looking for a some effective solution for powering our test cards to be tested under radiation. Each test card features 5 different FPGAs (Xilinx, Altera…
Part Number: LM43602 Other Parts Discussed in Thread: LM20333 Tool/software: WEBENCH® Design Tools When opening the design with the required values (VSON package, 5.95V≤Vin≤27.6V, Vout=5.12V, Iout=1A, 30°C), Webench simply states that this is not possible…
I have the LM20343 that not have the Spice Model. You have advised me to use LM20333 to perform simulations but LM20333 always operates at 200 KHz although fits a square wave signal (0V Low - High 2V) with frequency of 1MHz on the SYNC pin.
How can I…
Other Parts Discussed in Thread: LM20333 Hello,
We consider to adding the SBD to between L1 and PGND and between L2 and Vout for reducing the power loss during dead time. Could you please let me know if there are any concern? Best Regards, Ryuji Asaka
Hi,
We have noted that those spurious are generated mainly by the UCD7242 device that generates 0.95V (CVDDT1 rail 3 and CVDD1 rail 4). Reducing the frequency switching (from 751KHz to 300KHz) we have improved the EMC, but in order to pass the test session…
