Part Number: UC2843 Tool/software: Hello,
We are facing issue for radiated emission test with below section of UC2843 IC.
Observed around 78dBuV emission at 55MHz-110MHz frequency.
Below are the details:
Input supply: 24V, Output: Sec1- 24V/110mA…
Part Number: UC2843 Tool/software: Hi team,
Could you please share the Rohs test report of UC2843AD8TR? What we need is not ROHS statement, we need Rohs test report.
Part Number: UC2843 Hello ,
I have getting issue with output PWM duty cycle.
Even though I have given constant input at pin no 3 (Isense) Output PWM continuously vary, and flickering observed
Same solution I have used for different circuit it…

This is FAE Jayden, my customer is using UC2843DTR in their 12W flybuck power module. My question are below:
1. After measuring the chip case temperature…
Part Number: UC2843 Hi Team
Customer is using UC2843 as a buck controller. the waveform was shown as folloing when Vin-410V, and Vout=380V, Pout=1000W. and control circuit is shown as the second picture.
Can you help to show your insight in this phenomenon…
Part Number: UC2843 I am using UC2843 for converting 24V to (SEC1 = 16V and SEC2 = 16V) with dual secondary transformer as per below figure.
I am measuring Diode Q2 Drain to source waveform at typical load (at Secondary1 = 55mA and Secondary2 = 35mA…
