Part Number: UC3823 Hi Team:
My customer start to evaluate the ISG3201 in their power module, can you help to promote a pwm controller for us? tks in advance.
Other Parts Discussed in Thread: UC3823 hello'
I want drive two mosfet and i using uc3823 for that, the freq must to be 50Khz.
I need help how determine the freq by Ct Rt and ramp input. I using voltage mode at fixe duty cycle 50% and fix freq.
I try…
Other Parts Discussed in Thread: UC3823 Hello,
What is the voltage range for the non-inverting input (pin #2) and inverting input (pin #1) of UC3823?
Thank you!

Other Parts Discussed in Thread: UC3823A , UC3823 I am considering using the UC3823 PWM controller but I noticed that there is a UC3823A version also available. I would consider using the A version except that I will be driving SiC FETs so I need 20 volts…
Other Parts Discussed in Thread: UC3823 , UC3823A Hi,
On the datasheet of uc3823, the description of current limit reference (pin 11) is very short and followed by 'consult specifications for details'. What is the function of pin 11 of uc3823? I…
Other Parts Discussed in Thread: UC3823 I have two Cuk converters controlled by UC3823 and in order to connect them together, I have to figure a way how they can start together. Is there a way to synchronise two UC3823 PWM controllers so that they soft…
Hi,
I am working on a project that requires a PWM signal to drive a DC motor. We are using a DC voltage level to set the duty cycle. We want to use the IC in the subject line to generate the PWM signal, but I am not sure how to use the inputs, and I…
Part Number: UC3823A Other Parts Discussed in Thread: UC3823 , UC3823B Hi Team,
Could any expert help to check if we have any temp related characterization data for pin 9?
Etther UC3823/UC3823A/UC3823B is ok.
Customer is asking, thanks!

Hi Steve,
attached you find the schematic I draw above but add some additional information. We need a voltage controled buck converter (or a sync converter).
The isolated drivers are a good choice from you but I need the PWM controller with voltage mode…
