Chkv904g Circuit Diagram Full [VERIFIED]
When the original circuit diagram is missing, you become the detective. Here is a step-by-step methodology to recreate the full schematic from the physical board.
A: Not directly. Pinouts and internal reference voltages differ. Use only the exact replacement or a board-level repair. chkv904g circuit diagram full
| Pin | Name | Function in Full Circuit | |-----|-------------|----------------------------------------------| | 1 | VCC | Supply voltage (typically 12-18V from auxiliary winding) | | 2 | GND | Ground (primary side) | | 3 | COMP | Compensation pin for feedback loop (RC network to GND) | | 4 | FB | Feedback input from optocoupler | | 5 | CS | Current sense input (from source resistor of external MOSFET) | | 6 | RT/CT | Timing resistor/capacitor for oscillator frequency | | 7 | OUT | Gate drive output to external MOSFET | | 8 | HV | High-voltage startup (connected to bulk DC) | When the original circuit diagram is missing, you
In a full diagram, these pins are connected to a network of around 40-50 discrete components. Pinouts and internal reference voltages differ
