Part Number: UC3843 Hi, I have attached the schematic and transformer details of a UC3843 based power supply.
However, when I power ON the SMPS with 20VC, there is no output .
Kindly advise a step by step procedure to see why he power supply is not starting…
Part Number: LM5156 Tool/software: Hello again! I am revisiting use of the LM5156 after having successfully gotten the board to deliver the appropriate power at full load. We are now attempting to use the output of this board to directly connect to and…
Hi,
the LM5176 only support ccm of FPWM mode.
The MODE signal is a fixed voltage - defined by the resistor connected to that pin
Cycle by cycle limit:
If the current limit is detected the actual switching cycle is stopped and the device will wait for…
Hello. Thank you for your message.
I am attaching the results of the tip-and-barrel probe measurements you contacted me. This waveform eliminates significant noise. From the above, it seems that I was looking at noise on the GND wire and other parts of the…
Hi Rami,
It looks like the issue is primarily with your layut, as the schematic looks fine. I think the biggest takeaway at the moment is a lack of a ground plane and VIN/VOUT plane. I would refer to this blog post as guidance for reworking the layout…
Tahar Allag said: What the probe that you are using for this measurements? Are you using tip and barrel probe? because you may be picking noise in you ground if you are using long ground tip.
I am using 1Ghz High voltage Diffrential Probe.Attached the…
Part Number: BQ76940 Good day, I had just finished soldering components into my board ( https://e2e.ti.com/support/power-management/f/196/t/771358 ), and would like to ask if there's anything I should take into account before actually powering up my board…
