UCC27282: Oscillation on gate waveform in PSPICE for TI simulation

Part Number: UCC27282
Other Parts Discussed in Thread: CSD18537NQ5A

Hi Gate Driver Team,

Can I ask some questions while running the UCC27282 PSPICE simulation (Transient model from the ti.com product folder)?

(1) When I run the simulation, I can see a strange voltage peak at falling edge of LO and HO. Could you advise why it does happen?

(2) I replace the ideal switch to CSD18537NQ5A (plus decoubling capacitor (220pF), discharging path thru 100kohm resistor, gate resistor (1ohm)). I observe a severe oscillation on HO and LO. Could you advise why and how to solve it?

Your quick advice would be appreciated!
