Hi Payal!

Thanks for getting in touch today and for your interest in the UC3843 device! I can see your schematic attached here but I'm not sure what your input and output voltages should be. Can you provide waveforms showing the circuit behavior you are observing?

For some general tips on improving boost converter design and efficiency, see the following links: Basic Boost Calculations, Working With Boost Converters.

Thanks again for reaching out, I look forward to talking more!
