Hi Brenda,
Yes just adding the 3x22uF output cap will not get rid of the ripple significantly. You will also need a second stage LC filter such that the lower frequency component from PFM operation can be attenuated. This may require a rather larger inductor…
Part Number: TPS54495 Hi,
my customer would like to know the minimum input voltage for 5V output. the datasheet shows the input vs output voltage for 3.3V which gives a minimum input voltage of around 4.5V. Do you have the input vs output voltage graph…
Other Parts Discussed in Thread: TPS54495 Which side of is the inductor's pin 1 placed on - away or towards the TPS54495? It is not mentioned in the datasheet.
Thanks
Hi Rakesh,
Thanks very much for your help. I still have some questions. Although TPS25940 output is connected to the input of TPS61170, the drain of Q1 is connected to VBUS that is 24VDC.
I understood that the output of TPS25940 is connected to both…
