Part Number: UCC28C58 Other Parts Discussed in Thread: UC3842 Dear e2e support,
Our UCC28C58 offers a great pin to pin alternative to the UC3842; improving by ~10x the quiescent current.
Do we have any collateral (similar to our Design Note DN-89) to…
Part Number: UC3842 Other Parts Discussed in Thread: UC3845 , UC3843 We are building an MPPT tracker using the UC384* Family.
The tracker takes a voltage from 100V to 300V and outputs constant current with a voltage limit of 350V. The current is regulated…

Hi Experts,
I am posting this on behalf of the customer. Here it is below.
I'm designing a boost converter based on UC3842 as in the pdf file attached. It is showing instability when in full-load operation. Could you please…
Part Number: UC3842 Hello everyone,
I am a student, and I am building a LED driver for my project.
I'm using the UC3842 as my control IC for the flyback converter. While designing the circuit, unfortunately I did not implement a soft-start circuit for…
Part Number: UC3842 Other Parts Discussed in Thread: UC2825 Hi,
Is there any current mode controller that supports up to 600V input voltage and external reference set?
Thanks,
Part Number: UC3842 Hello,
I am building an Emergency Power supply using flyback. My input voltage is 400V and output voltage is 12V. I am using peak current mode control. Can I use this configuration with auxilary winding for UC3842?
Part Number: UC3842 Hi TI's taem
We want to use UC3842 as a Voltage Mode PWM.
Do RT/CT circuits need to be connected like the below picture from datasheet?
Can it be connected like the typical circuit (just using a resistor and capacitor)?
Will the…
Part Number: UC3842 Other Parts Discussed in Thread: UC3844 , Hi
How can we check the open loop test of uc3842/uc3844?
I gave
Vcc = 17V,
Vfeedback = 2.5V externally
Isense = 0.5V externally
When applying all these voltages, the output pulse I'm getting…
Part Number: UC3842 Hello All,
I am a student trying to build a LED driver circuit for my project. I am trying to power up the circuit step by step to check for errors. I have a ready PCB with all the components on it. I am trying to see if UC3842 is…
