Other Parts Discussed in Thread: TPS54160
Hi, support team
When testing PMLKBUCKEVM, it was found that at light loads, the Vnode waveform seems to have some oscillations at higher input voltages.
CH1 represents Vin, CH2 represents current ripple, CH3 represents output voltage ripple, CH4 represents Vnode.
In addition, the manual says that the TPS54160 should be based on the external resistor to set the frequency, in the case of a fixed resistor why the frequency changes in such a large range?
Thanks for your support.
