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: 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,
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…
Other Parts Discussed in Thread: TPS64203 , LM5085 , LM5088 Hello TI --
I'm interested in building an AC supply for a microcontroller/WiFi combo, with 120VAC input and 5VDC output. To save on cost and space, I liked the idea of a transformer-less design…
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…
