Part Number: UC1823
My question deals with the output stage of the UC1823. I am using the UC1823 output to drive drivers that are 5V input rated. So I am running the 5V VREF voltage into the VC pin and getting good results in the lab with it driving…
Part Number: UC1823 Other Parts Discussed in Thread: UC1825 Hello,
I'm having trouble finding a spice model for the UC1823 device. Is there a spice model available now?
Thanks,
Adam
Hi Jeremy,
Did you get the model from certain group inside TI or from FAE representative perhaps?
I could not locate this model from any of our system especially under the "Tools & Software" section of the product as shown here www.ti.com/.../UC1823…
Part Number: UC1825 Other Parts Discussed in Thread: UC2842 I was looking for a spice model for the UC1825. I saw this response( https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1077855/uc1823-ltspice-model-download…
Part Number: UC1823A-SP Other Parts Discussed in Thread: UC1825 , UC1823 Hi!
Can I use the spice model of UC1825 to perform analysis to a design that is using a UC1823A-SP?
The only difference between UC1823 and UC1825 is the max duty cycle limit…
Hi,
UC1825A two outputs are alternately controlled, each output has up to close to 50% duty, two outputs together have similar close to 100% duty. So on the same setup, Fig 3 can be used for UC1823, and for UC1825, Fig 3 is for two outputs together…
Part Number: UC3823A Other Parts Discussed in Thread: UC1825 , UC1823 Short description: Unable to obtain PWM duty cycle of less than 30% with UC3823A.Case details or comments:
When error amplifier output voltage (pin 3) is lowered, the duty cycle reduces…
Hi Peter,
Thank you for taking time to respond to this issue. Does this also apply to the UC1823 and UC1824, which we also use? Can you tell me the nominal zener clamp voltage for the 1A ESD device? Would like to know the value to assess the nominal…
