SY8089A1, Silergy, stepdown converter, marking qHxyz: https://www.silergy.com/zh/download/downloadFile?id=3756&type=product&ftype=datasheet Check the devices connected to the output side of the inductor. They could be overloading the IC. |

They could be overloading the IC. Thanks! Out of curiosity, how did you manage to find the component based on the marking alone? I searched for quite awhile and couldn't determine what it was. Maybe I'm not searching properly or not using the right resource. As far as the output side of the inductor, the only components connected to the output of the inductor is another inductor, 3 capacitors, and a resistor. The inductors are good and none of the caps are shorted. Resistor measures at 100k. Going further down the circuit, it leads directly to the NAND. SY8089A1 Pin 3 (LX) ---> L1 inductor ----> capacitor and L2 inductor share output side of L1 -----> L1 inductor ----> 2 capacitors -----> 100k resistor ----> NAND The other components seem ok and there are no shorts on them, so I am assuming this SY8089A1 is the culprit. I really quickly drew out the circuit to show the other components. Unless I am overlooking something, it seems I probably just need to replace SY8089A1, right? Attached pic and the component on pic 2 is the 100k resistor

The marking style reminded me of Silergy, plus I was familiar with the way that Silergy's datasheets identified the marking code. https://www.google.com/search?q=filetype:pdf+"absolute+maximum"+qhxyz+silergy I use "absolute maximum" to filter out spammy web sites. Measure the voltage at the output. I expect that you should find 1.8V or 3.3V. |

Also, wanted to mention that the only other component that is heating up is the controller which is a Realtek RTS5733DMQ |

The feedback voltage is 0.6V, which means that the device is regulating properly. A supply of 1.1V would be the Vcore for the controller. |

Any ideas why this drive isn't detectable? i have SSD like yours and the controller is shorted with mine cause i becomes very hot when i connect the power did you resolve your case ? |

Hello, i have the same disk with the same problem. did you manage to solve the problem and recover your data? |
