The target Vout is 10V. Vin is 20V
The switching waveform is stable at loading < 0.01A, the switching frequency is 11kHz.
When the loading > 0.01A, the waveform becomes unstable.
The TI flyback IC -- LM25180NGUR, But the flyback converter seems oscillating, below are the primary switching waveform & schematic. Do you have any comment or experience in this case?
