Hello,

I have chosen 3.5-20V input and output of 11.5V ,100mA.Problem is that switching is not taking place. I have skipped the comp pin circuit .Does it has anything to do with the comp pin circuit.

Also i have used Rt 12kohm

Hi akanksha,

Can you share the simulation file?

Hii,

I made some changes and the circuit worked ..with no load scenario....but as soon as i applied 197ohm resistor the input voltage dropped from 4.0V to 2.8V and same with output instead of 11.5V it dropped to 1.6V ...what could be the possible reason?

Hi akanksha,

Can you share some waveform if you are talking about simulation?
