They form the classic compensation network. My original idea was to change the voltage at the sensing pin of the IC wich turns to be IN to fool the IC into changing the duty cycle and thus making the output voltage higher or lower. My board has 3 transformers main, secondary. Extra rules apply to questions on vehicle electronics – please read before posting.
What you should look at is the pins 17 and But there’s absolutely no change. The opto is only used for the standby-PSU.
Ask the mods before posting. Modifying an electronic circuit or product at component level. First, check out our list of national and global suppliers. If the sd6019 are defective, please notify us within 3 days of delivery.
I believe if I can adjust the voltage on the IN pin with a variable resistance I can trigger the IC into thinking there was some voltage drop or up in the output and therefore, the IC would try to compensate this voltage by adjusting the duty cycle, thus making the output voltage up or down.
That is not something that will happen when changing R57 or VR2. I tried on both reference pins 12 and Built-in high precision oscillator provides accurate protection and delay time for monitoring. Sample Order Paid samples.

Original new IC SD6109
The positive input of error amplifier I is connected to 2. Note that there is something wrong in the datasheet, because it appears that both R19, R18 and U1 are in series xd6109 shorted to FB2. I AC fail detection. I’m I missing something obvious?
