Part Number: UC3842 I used UC3842 to design a 30V-60V Boost circuit,but the curent sampling resistor always burnted out.What's the possible reasons?Thank you!
Part Number: TL494 Other Parts Discussed in Thread: UC3842 Hello,
I want to design SMPS using TI's UC3842 for 12V,10A(Isolated Flyback) also 24V,10A SMPS using TL494(half bridge).I also tried using Webench but could not find UC3842 and TL494 reference…
Hi Manjunath,
I haven’t heard back from you, I’m assuming you were able to resolve your issue. If not, just post a reply below (or create a new thread if the thread has locked due to time-out). Thanks.

Part Number: UC3842 I have built a non-isolated boost converter which should operate with 1-phase rectified DC as well as three phase rectified DC. I have validated the converter for three phase rectified DC and now I am trying to operate converter with…
First I must apologise for taking up so much of your time and for what must be a rather frustrating continuing saga! You have probably guessed that I am working at home with some basic kit. However, I have done some screen shots which are pasted below…
Other Parts Discussed in Thread: UC3842 In the UC3842 datasheet, there are some questions on an application circuit.
What's the purpose of the D3 and C4? Why there two diode rectifier in the circuit?
What's the purpose of the R9?

Part Number: UC3842 Other Parts Discussed in Thread: UC3843 Hello, I used UC3843 to make a 2W winding feedback flyback IGBT drive power supply. The circuit block diagram is as follows:
The circuit is a conventional flyback circuit. The control winding…
Part Number: UC3842 Other Parts Discussed in Thread: UCC38C42
For the example in pdf I have not found a formula for finding the number of turns in the primary and secondary winding starting from the primary and secondary inductor of 1.5mH and 15uH respectively…
Other Parts Discussed in Thread: UC3843 I already have a source SMPS using this component that meets my needs. X 12V 6A. Photo attached.
Now I'm developing a smps with symmetrical output +/- 35V x 3A for audio and +/- 15V x 500mA for pre-amplifier.…
