TPS5402: TPS5402DR: Component Selection

Kosta Kotsis

Part Number: TPS5402
Other Parts Discussed in Thread: TPS54202, TPS54302, TPS62933

Hello all, 

I am trying to use this DC/DC converter as a buck converting the input voltage of 24V to an output of 5V. 

However, the datasheet seems to be lacking crucial information regarding the selection of many components, including here Rfb1 and Rfb2. 

Is there any other source with additional information regarding the selection of these (and other) components for this chip? 

Furthermore, is there any spice model for this component?

Looking forward to your reply. 

Best regards, 

Konstantinos Kotsis
