Mb1364 | Schematic

If you are reading this, you likely have a piece of gear on your bench with a dead "MB1364" module, or you are staring at a PCB with that silkscreened on it. The bad news is that a dedicated, standalone datasheet for the "MB1364" is surprisingly rare in the usual channels (like Alldatasheet or Datasheet Archive).

| Pin | Symbol | Function | Typical Voltage | | :--- | :--- | :--- | :--- | | 1 | Vcc | Supply voltage (via dropping resistor) | 12V - 15V | | 2 | GND | Ground | 0V | | 3 | FB | Feedback from secondary side (opto) | 2.5V (Reference) | | 4 | Out | Driver to switching transistor (Base) | 0.6V / 1.4V switching | | 5 | CS | Current sense (connects to emitter resistor) | < 1V | | 6 | NC | Not connected (isolation slot) | - |
