Is there a spreadsheet available to download to use to plug in the numbers for a TPS40210 design?
I am having difficulty to get a 22VDC to 36Vdc in, and 210VDC out, at 4mA to work.
Some of calculations seem unclear.
Some Equations indicate say Fosc is in Hz, and other times in kHz. So using 200 or 200,000 becomes unclear.
Using the Rt Equation on P15 7.3.5 I get a Rt of 389 Ohm, which can not be right.
Any help appreciated.
