Part Number: TPS54328 Can we use TPS54328 VREG5 output for external circuit until 60mA?
We would like to use VREG5 output for LED current source. LED current is about 10mA. Is there any concern?
Best Regards, Kohei Sasaki
Part Number: TPS54328 Hey team,
I have an application that is taking 12V in to 4V out using the TPS54328DDA, and due to the large output capacitance on this design the 4V output remains after the 12V input goes to 0 and the input side starts to backed…
Part Number: TPS54328 Hi,
Does the TPS54328 discharge output caps actively when EN goes Low or VIN reaches down to UVLO threshold?
If yes, how does TPS54328 do it? (Low-side FET turns off? or any other discharge circuit exist?)
Thanks,
Go

Other Parts Discussed in Thread: TPS54328 Hi,
I tried TPS54328 Webench simulation, and I find the max current set 2.5A in Webench.
Why is the max current limited a little bit lower than TPS54328 current rating?
Thanks

As datasheet describes,if the over current condition exists for 7 consecutive switching cycle,the internal OCL threshold is set to a low level.customer want to know:What is the low level of threshold value?In low level threshold value,what is the actual…
As a first approximation, you can say that Fsw = 650 kHz and minimum off time is 310 nsec. So maximum duty cycle is about 79%. If you have 5.3 V output, then that will require 6.4 V input at no load. You can also figure in the loss terms as a second order…
