Part Number: UC2844 Hi
When starting the VCC voltage, it is found that the VCC terminal voltage is basically equal to the input voltage of 100V, and the normal VCC end has a voltage regulator clamp, which should not be 100V
Part Number: UC2844 Hi team
Could you explain the role of the portion circled by red below? And could you also explain how this figure 8-13 works?

Part Number: UC2844 Dear team,
What is the rated power of this TVS diode? Customer is doing Safety function by calculating how much voltage will damage the push pull output of UC2844.
Part Number: UC2844 Dear Support Forum,
I am having troubles getting a clean gate signal using a UC2844 in a Flyback SMPS.
So I built a simple UC2844 test circuit as shown below. Note the load is a 1.8K resistor. I am forcing the PWM output to be 50%…
Part Number: UC2844 Hi expert,
My customer wants to add a protection circuit to protect the UC2844.
It is to detect the voltage of the comp pin. Under normal load conditions, it should be between 0-4.5V. If the auxiliary source output is short-circuit…
Part Number: UC2844 Other Parts Discussed in Thread: UC2842 , Dear team,
My customer asking me the function safety related question about the failure mode if duty cycle greater than 50%? I saw in the block diagram our UC2842 VS UC2844 differs in T flip…

Demand: 16-36V input, isolated output 24V current 1.4A
I see that the parameter of UC2844 manual is 12-30V input, but when using WEBENCH Designer for reference design…
Part Number: UC2844A Other Parts Discussed in Thread: UC2844 Hi,
Planning to make new SMPS design, previously had used UC2844 and external FET, in almost all of my Flyback converter design(20-60W) since last few years.
Input voltage range: 200VDC to 800VDC…
