TIDM-1001: TIDM-1001 PWR050 SCH

Hi,

Due to US holiday, the subject matter expert will respond to you tomorrow.

Thanks & Regards,

Santosh

Hi Please find the schematics in the link below.

Thank you!

Could you help to find the application note of this demo?

What is the the 400V monitor sampling circuit PIN6 voltage GAIN VS the 400V input? how to calculate the gain ?

In the SCH,400V=1.5V,how about 300V=? and 200V=?，

Hi I was not able to find any app note. You probably want to check the components datasheet and also do the circuit analysis to figure out if it works for the conditions described.

HI 

 I am very confused which one is the right gain.For the reason in TIDM-1001the PWR 050 SCH ,written that 400V=1.5V,while in another application noteTIDA-00381  that use the same PWR050SCH,that written 400V=1.96v.So please help me to make sure the right gain of PWR 050 VIN MON. Thank you!

Not sure if any hardware difference, but I would suggest follow whichever ref design you are referring to.

The TIDM-1001 and TIDA-00381use the same PWR050,but written the different Vin MON Gain

Could you help to ask other more senior TI experts to reply this problem?

Do you have either TIDM-1001 or TIDA-00381 hardware to do some test/measurement? If so, could you measure the pin voltage level?

I cannot assign the task to another person, but you could try to post your questions under TIDA-00381 instead of TIDM-1001 to see if that helps.
