Forum Post: 40W circuit,output 40V@1A

sir,

I have been working on 40W driver with output 40V@1A with TPS92210.

I need input OVP/UVP protection circuit.

Its been tried but till now I have not achieved a right solution.

There had been use of 4 transistors ,still there was flickering in range of upto 4V at lower and upper cut off as well.

Could you please guide some way?Or if there is some repalcement IC which has inbuilt input OVP/UVP and thermal shutdown properties.

Regards,
