UCC28950: Switching frequency of 400 Hz

Liu Yang

Part Number: UCC28950

Hi Team,

I want to operate the switching frequency at 400 Hz, is it possible?
If possible, does any effect of low frequency occur in this IC?

Hi Tom,

UCC28950 can support frequency between 50kHz~1MHz. There is no way to let this controller to work at 400Hz.

Hi Huang,

Is there any PWM controller that can support full-bridge and 400 Hz?

Hi Tom,

I try to find all the full bridge in TI website, unfortunately I can not find a controller from BU to support such low frequency.
