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.

Part Number: UC3843 Dear Sir,
We are working of bring up and testing of DC-DC (Flyback) Converter (VIN: 32 to 75V DC and output 24V and 15W) based on UC3843, We are getting multiple pulses on Gate (Magenta Line in the waveform) and MOSFET Drain to Source…
Part Number: UC3843 Hello,
I was used UC3843 with SOIC8 package with 12v Supply voltage,but it is start heating after giving supply voltage without any input given to IC. We used UC3843 as PWM generator with analog input on Isense input pin,
Heating was…
Part Number: UC3843 Hello Forum Members,
I have got a UC 3843AN based laptop SMPS. The pin 2 (FB) is grounded. The supply is out of order with a fuse, bridge, MOSFET, Rs all damaged. Is there any reason for UC 3843AN pin 2 (FB) being connected to supply…
