TPS62932: Ok to implement a flybuck ?

Hi Ue,

My colleague will give you reply by tomorrow!

Hi Ueli

It depends on the output condition of the application. Firstly, you may choose the ratio of the primary turns VS secondary turns for the transformer and then consider the primary inductor current using secondary current, primary load current and the ratio. If the inductor current would not have negative value, it is ok to use a ECO mode device. But if it has negative value, you must use a FCCM device like TPS62933F and consider the valley current not exceed NOC of the device.

Hope this helps.

Hi Ruby

Thank you for these comments and agreed, I would also think that one must use the TPS62933F to implement a Flybuck.

Do you have a reference design that the customer could use as a starting point for:

Vin= 12V ... 28V, Vout=5V, Iout=100mA

.... or other helpful collateral for implementing a Flybuck with the TPS62933F ?

Best regards

Hi Ruby

Thank you for pointing to the app not.

I am also looking forward to the same for the TPS62933F.

Best regards

Ueli
