Purchased a device from an online retailer (fairly well known and reputable), they ship from internationally and often include a local USB wall charger to replace the one in the box of their goods.
Plugged said charger in and it blew immediately. Pulled it apart (because curiosity - it's worth a few bucks so I wasn't bothered to return it). Turns out the control chip (DK112) blew. Had a closer look and noticed something interesting on the underside - does it make sense for that resistor to be there shorting the pins? Worked out that it is between the GND and Collector pins of the chip.
Just curious as to whether the fault is in the circuit design or the chip itself!
