Whether the KF8 become master chip in the AC/DC ?

Just want to hang out with other Makers and chat about stuff? This is the place to do it.

Whether the KF8 become master chip in the AC/DC ?

Post by ling1995 » Thu Mar 16, 2017 6:35 am

Hello~friends,please allow me to express my appreciation to you for taking time to read my post. I’m in hot water now, anybody could help me?

AC/DC need to measure the current and voltage when inputting.The KF8 can be measured by AD.I would like to know if it can pass the detection feedback of AD at the same time and drive MOS by controlling PWM? The switching frequency is about 100KHZ.When the 220AC inputted and 12V 2A outputted, We will get a feedback of 431+PC817. In such a situation,Can KF8 be the master chip? (this is KF8’s datasheet:http://www.kynix.com/uploadfiles/pdf9675/KF80BD-TR.pdf) Could you give me some advice?

Thank you in advance!
