Part Number: UC3843 Hi, Please refer to the application note SLUS223E for IC UC3843. Please refer to figure 25 on page 22.
I am designing a DC-DC converter. The DC input voltage will be 18-25 VDC and output will be 15V, 1A.
Now, the supply voltage…
Hi Payal! Thanks for getting in touch today and for your interest in the UC3843 device! I can see your schematic attached here but I'm not sure what your input and output voltages should be. Can you provide waveforms showing the circuit behavior you are…
Part Number: UC3843 Hi,
My customer want to confirm how much pulse width "D" varies as Vfb varies. Is there any equation related between the two?
Thank you in advance.
