Part Number: TPS64203 Hi Support,
Some questions regarding the switching freq of the TPS at almost no load for both boards. Can you adv the reason?
I attach the waveforms for Board 5 and Board 7 for the VDD3.3.V.
For Board 5, the sawtooth frequency of…
Part Number: TPS62A01 Other Parts Discussed in Thread: TPS64203 Hi Experts,
Good day. Initiating this thread from Dietmar (customer), raising technical concerns with TPS62Ax application in placed of TPS64203.
We use an TPS64203 for a Wide Range DC/DC Converter…
HI,
I am developing a source AC/DC non isolated with the following characteristics :
Vin = 120-230V.
Vout = 5V @ 750mA.
This layout is good? I have based on the PMP5412 . This PCB is only for tests, the final version will have reduced dimensions to fit…
Other Parts Discussed in Thread: TPS64203 hi,
I am working with TPS64203 IC. But, the hard part is detecting whether the IC is placed correct or upright. I am having a hard time with deciding it due to the absence of notch in that IC. So, please help me…
Part Number: TPS40041 Other Parts Discussed in Thread: TPS64203 , LM5169 , LM5164
Hi,
I'm in need of a synchronous (for high efficiency) DC-DC buck converter with a 120V (max) input and 3V output. Is it possible to use TPS40041 where VDD is initially…
HI Jeff,
Many thanks for your quick answer, it is really appreciated. According to your comment, PFET that allow low power dissipation are quite expensive and not easy to find. We could expect that power dissipation could also become an issue in the passive…
Other Parts Discussed in Thread: TPS64202 , TPS64203 As it is not described in the datasheet, I'm looking for informations about the TPS64202 (or TPS64203) current limiter.
Does it work when the device is in 100% Duty Cycle Mode?
Is the transition between…
