UCC28063: Apply 10KΩ to PHB

Part Number: UCC28063

PHB is basically connected to VREF and 0 ohm.

Is there any part that affects circuit operation when this part is connected with 10k ohm?

Can this affect the Impulse test?

Hello Kim Andy,
If PHB is connected to VREF with a 0 Ohm jumper or with a 10k resistor there should be no difference in operation provided there is no resistor from PHB to GND. Also this should not affect the results of the impulse test but the best way to find out is to change the do the test with both value and check your results.
