Increase the footprint size of C461 to 0603 and increase the value of R418 to 33k in order to be able to use common 1uF 0603 capacitors rated for 35V

The worst-case OVP with R417 and R418 being rated at 1% is 34.96V which is still below the 35V rating. The output voltage is typically 22.4V which is well below the voltage rating. Therefore these capitors should never experience a voltage above what they are rated for.
