Posted on May 16, 2012 at 06:08I have an application where i need to use Viper25H in non-isolated mode.For reference generation I am using TL431. But the problem is that when TL431 is used for non-isolated configuration , power supply is getting int...

Posted on November 08, 2011 at 11:01In my design iam using Viper25DTH. My o/p power is upto 6W i.e. 4.1V@1.5A. But whenevr i am ging 1W load, the voltage on VDD pin starts to oscillate between 4.5V to 15V and feedback voltage is upto 3.4v, it seems ...

Also suggest, if the maximum injected positive current is 10uA for contiunous period if 8-10 hrs, would it still effect the reliability of GPIO

Ya but the datasheet specifies 0mA positive injection only for 3v and 5v tolerant pin, and specifies NA for for other . What does NA means

Posted on January 03, 2012 at 11:34Sorry for the very late reply. I have solved the problem. I have coming up with a new problem. 1. Earlier my design was for isolated smps, but i need to make it to non-isolated smps. For this i replaced the opto fr...

What is the maximum value of positive injected current in 3V compatible I/O for STM32L476 micro. Also what will be the maximum allowed input voltage in Pin when Vdd is 0V.
