I am using LM5022 to boost voltage from 15V to 60V. But I am getting output as same as input. Kindy suggest.

Hello Saravanakumar,

Thanks for reaching out to us via e2e.

The UVLO pin needs a voltage of 1.25V to start the device. Below that voltage it will hold the controller in reset.
With your chosen resistors (10k and 768R) you will need to supply a minimum of 17.53V to bring the part out of reset.

Best regards,
Harry
