Jonathan: The simulation model of ADuM3190 is now on our website under the product page for the ADuM3190, the link is below.
During startup, output of primary amplifier (eg EAout2) is at high level when VDD2 is lower than 3V.
How to avoid this behaviour when ADUM3190 is included in a regulation loop.
Sartup is impossible due to the wrong information sent to PWM controller…
I'd like to use the ADuM3190 in a DC/DC converter project. For this purpose, I'm trying to build a simple PSpice model of the ADuM3190.
What I need is some information about the DC transfer characteristic of this device.
Using my Pspice…
Devarajan: In response to your questions:
1. I checked, we don't have EMI radiated emissions data on the ADuM3190. I just returned from the emissions lab for another product. I don't have emissions lab tests scheduled. Next time we go, I will…
Alexander: The ADuM3190 is a isolated error amplifier and as such was not designed with a high input impedance. The high input impedance source of 71.5K is not a good match for the input impedance of the ADuM3190.
Irvin: If you use the ADuM3190 as a linear isolator, the input to output gain will vary from 0.9 to 1.1 or +/-10%. But, if you are isolating a feedback voltage you may want to use the ADuM3190 as an isolated error amplifier and use the 1.225V internal…
