Part Number: UC28023 Other Parts Discussed in Thread: UC28025 , Hi
We use UC28025 today and are looking at the UC28023 and have two questions. One about pin 11 on the UC28023 and one about setting max duty cycle for the UC28023.
Is pin 11 on UC28023…
Part Number: UC28023 Please attach the PKG dimension and the explanation of Solder Mask detail and Solder Paste example because these data are not shown on the data sheet (SLUS557G –MARCH 2003–REVISED DECEMBER 2016),even though stating on the other similar…
Hi Lars,
The ILIMREF pin on the UC28023 is used to set the current limit threshold externally. This is for current limit protection, not for the topology peak current mode control law implementation. You can use a resistive divider off VREF to set…
Part Number: UC28023 Hello,
I am considering using this controller IC UC28023, but I need to be able to drive a synchronization clock to the device. In the electrical characteristics section it specifies it only as an output pin.
In another…
Part Number: UC28023 Hello.
I have a question about UC28023.
There is MAX duty 80% (min) of UC 28023 in the data sheet. Is it possible to construct a forward converter with duty MAX: 80% by setting external constants? Also, is duty MAX: 50% general…
Other Parts Discussed in Thread: UC28023 Hello
I have two questions about UC28023.
1.This device seems to shut it down when I apply signals more than 1.4V to ILIM/SD terminal (9pin),
will a latch work then?
2.I design circuit that Vref is…
Other Parts Discussed in Thread: UC28023 I Have a Technical Question regarding the UC28023 - High Speed PWM controller. I expected the specification to be found in the datasheet, but it is not. The Soft-Start Pin (pin 8) allows me to linearly charge the…
