Hello. I have tried to identify the following IC. As i can see from the other components near to it this is a bulk dc converter controller but i cannot find which one. Thank you for any help |
| Vicus:
Can you identify the pin function? Are you shure is not a linear device? Where is the coil? |
| spetros:
Thank you for your answer. I am attaching another one photo of the board with some components removed. I am sure because it takes 12V and at the outputs 5V |

The topology looks more like a boost converter with an output voltage of 12V. Pin #3 looks like the feedback pin, with the FB voltage being 1.0V. Vout = 1.0V x (100K + 9100) / 9100 = 11.99V |

Thank you for your answer. I attach the circuit diagram of the unknown ic . Maybe it will help to identify it. Edit ( The diode is not shottky but a diode with marking L2V9 which is unknown too ) Also i have found the same IC but with marking AJ2hD from another same board |
