TPS55330: TPS55330 efficiency

Hi Max

Just let you know the expert is out of office. Please allow us reply next week. Thanks for your kind understanding.

Hi Max,

I only have the 5Vin/8Vo efficiency at fsw=300kHz.

Eff=86.1% with a 10mA load current;

Eff=48.3% with a 1mA load current;

When operation frequency higher, the efficiency will be lower than the above value.

Now our PHX team support this part.  If you want other data, they may help you if they have time.

Thanks Helen.

Do you have suggested diagram for a flyback configuration to produce 170v or do and about 2mA with efficiency chart?

Hi Noi,

Our expert in PHX  team will help to answer your question, they are quite familar with the flyback design.
