UC2846: Inquiry Regarding Isolated Reference for COMP & EA- Pins in UC2846

Part Number: UC2846

Tool/software:

Dear Team,

Greetings!

We are currently working with the UC2846 Current Mode PWM Controller and noticed that its reference design does not include an isolated reference for the COMP and EA- pins.

Could you please advise if there is a recommended method to provide an isolated voltage to these pins?

Best regards,

Hi,

What is your converter topology? A converter like flyback and forward, usually an opto coupler is used for isolation.

Please provide your design details in a circuit drawing to help understand what you need.

we want to use design DC -DC convertor using UC2846 IC , this IC used Push Pull configuration.

Thanks
