Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843A
Hello
I am having an issue with the comp pin in the UC1843A spice model being able to be pulled down to regulate the duty ratio. It is used in the feedback loop with the FB pin to gnd so…
Part Number: UC1843A-SP For the HKU pkg (5962P8670409VYC), I see that the lid is metallic and connected to the thermal pad. Is the thermal pad internally connected to GND?
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843A Hi,
I am planning to use UC1843A-SP for the flight model in my design. Before using it, I will use UC2843AN or UC2843N for the prototype instead of UC1843A-SP. I didn't see detailed information…
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1844A ,
Hi,
I'm planning to drive my FET with 300kHz switching frequency and %50 max. duty cycle. Therefore, I'll try to set the internal oscillator to 600kHz.
However, when I arrange it…
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843A , Hi,
I'm trying to find some formula and technical notes about how to design feed-forward compensation network for my dc-dc application.
Please provide me some technical note to do it…
Part Number: UC1843A-SP Other Parts Discussed in Thread: TINA-TI
¨Dear TI Teams,
I have tried to install and use PSPICE FOR TI but I'm strunglling simulating a ,simple circuit with the UC1843A-SP PWM controller. The schematics is shown below…
Part Number: UC1843A I'm getting the dreaded "time step too small" error while trying to simulate a flyback controller using the UC1843A-SP model downloaded from the product page. The same circuit, but using the built-in LT1243 controller, is working…
Other Parts Discussed in Thread: UC1843A , TINA-TI Dear TI,
(edit change UC1483A to UC1843A)
I'm trying to run a simple simulation moving from TINA_TI to SPICE FOR TI, for simulatiuon capabilities purposes (Monte carlo and so on). The schematics is as…
Part Number: UC1843A-SP Other Parts Discussed in Thread: UC1843 I would like to shutdown the UC1843 (space-grade part is what I am using) and would like to know what the supply current would be if I did that. I would shut it down by one of the methods…
Part Number: UC1843A-SP Hello,
I am looking for an app note or an example layout for the 20-pin UC1843A-SP LCCC package.
The circuit is driving a low-side NFET for an LED control application.
The biggest concern is the proper layout connections for…
