Part Number: UC2842
Hi,
I am using two UC2842 IC for interleaved boost converter with external clock synchronization at 180 deg phase shift . Below is the connection to make the current reference same for the both the PWM controller.
Please review…
Part Number: UC2842 Hi,
I have read datasheet of UC2842A and application circuit ( calculation ).
Questions :
1. Snubber Circuit ( RCD snubber selection ) Calculation not specified ? Please give the calculation details.
2. Is there any Simulation…
Part Number: UC2842 Hi E2E,
Good day!
A customer of mine would like to know the purpose of the RT/CT transistor on figure 25 of the UCx84x datasheet.
Best regards,
Franz
Sancar,
If you see a "sawtooth" on VCC and bursts of pulses on OUT, this is describing a start-up problem. Here are some suggested debug things to try:
Solder flying wires so you can connect a DC lab supply directly to VCC, Apply a small signal…

Hi, Ti member
We are developing the buck converter based on UC2842. Instead of current mode, use voltage mode refer datasheet and add additional OPA circuit to limit output current.

Part Number: UC2842 Just to note to who can be interested, in case no one was aware of it, of a question on a circuit in the datasheet modified in April 2020. The problem is illustrated by Dr Sam Ben-Yaakow in his you tube post: https://www.youtube.com…

For UC2842, the datsheet says "never" use RT < 5 k. The osc timing graph in Fig. 10 shows RT >= 5 k always, so it's not allowed to use RT < 5 k.
As I asked above, what Dmax does the customer require? Why are they using RT = 680 ohm?
