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: UC28025 Other Parts Discussed in Thread: UC28023 , , UC1823 Hi,
Could you provide the fomuler to give soft-start time with using SS capacitance, charge cerrent from SS pin, and final voltage of SS pin - the voltage value may be as same…

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…
