I am designing a new SMPS for my project I need 350mA at 15V but I could not get more than 100ma. when I reach to 100mA output voltage was start to decrease. when current goes to 200mA, output is like a sinusodial signal from 9v to 15V. I design my SMPS with E-design suit but its not working stable. I need urgent help
I was changed my topology to Viper222XS because of your heat suggestion. But I have same problem with new IC
I was built my project with belowed shema but when its going to shutdown when current is going to 400mA. My circuit is start with 100mA but when pust to start button its going to 400mA immidiatly ( its like inrush current) and Viper will going to shutdown and start again 1Sn later
is there anywhy to disable over current protection ?
Just I could not find 1.2mH coil and I was used 1mH coil with belowed datasheet
