Part Number: TPS54525 Hi Expert,
My IPC customer would like to confirm the adjustment range (min and max values) for the soft start capacitor of TPS54525 and If exceeds the designated value, will it have any impact on the IC?
Currently, they are considering…
Part Number: TPS54525 Other Parts Discussed in Thread: TPS54325 In TPS54525 the power good function is set to Low before EN and soft start.
where as in TPS54325 the power good function is set to tristate before EN and soft start.
why this difference in same same…
Hi Chrisitan,
I did not replicate such phenomenon on EVM, TPS54525 restarts after such Vin drop. Perhaps I need for information from you.
Could you please help to share layout of TPS54525? How could you achieve 400ms delay in circuit? Could you please…
Part Number: TPS54625 Other Parts Discussed in Thread: TPS54325 , , TPS54525 , TPS54425 Hi Team,
Just want to double check, is TPS54325, TPS54425, TPS54525 and TPS54625 function equivalent and pin-compatible?
Customer is now using TPS54325 and TPS54425, but…
Part Number: TPS54525 Dear colleague,
Our board now uses TPS54525 to generate 3.3V power from 12V, and 12V is generated from 220V AC with AC-DC module. Now we have observed such a phenomenon. Several boards share a power supply strip, and the 220V AC…
Dear Zhao
Thank you for your reply.
I got the waveform you requested from our customers.
(In these two waveforms, the PG pin is connected to the VREG pin as shown in the following circuit. The resistance between the PG pin and the VREG pin is
being confirmed…
Part Number: TPS54525 Hi team,
I want to use this device as below, Vin=5V, Vo=3.3V, Io=5A; if I connect 3000uF in the output, will it have any bad impact? Thanks.
Part Number: TPS54525 VIN's operating range of TPS54525 is 4.5 to 18V. Does that mean as long as VIN is within this range, PG would be driven LOW while EN is LOW? May I know the time delay from VIN reaches 4.5V to PG got driven LOW while EN is LOW…

Part Number: TPS54525 Hi team,
My customer is asking the behavior of current limit.
Could you tell me how the IC behave when the output current is over current or flow the max current continuously? Will the IC get high temp or burn?
