Started: adding UC3825 timing and driver parts.
Thought for 9 sec
Core parts are in place. Next I am wiring the UC3825 oscillator, control loop, and the dedicated 15 V gate-driver output stage around the placed parts.
Thought
Work done
- Renamed the project to UC3825 MOSFET PWM Driver and updated the description for the approved PWM/gate-driver goal.
- Documented the chosen architecture and timing assumptions in Design Notes.
- Added the full initial schematic part set: U1 as U1, U2 as U2, timing parts R1 and C1, control potentiometers RV1 and R2, support passives R3 to R7 and C2 to C9, plus output connector J1.
- Verified the placed parts and pin names for U1 and U2, and extracted key datasheet constraints for decoupling and gate-drive implementation.
Success criteria review
- ❌ U1 is not yet wired, so the UC3825 timing network is not implemented or verified at 10 kHz.
- ❌ The two potentiometers, RV1 and R2, are added but not yet connected for frequency and duty control.
- ❌ The gate-driver/output stage around U2 and J1 is added but not yet wired, so 0 to 15 V output operation is not established.
- ❌ The full schematic still needs net connections and verification.
Next steps
The remaining work is to wire the full schematic: add the 15 V and ground rails, connect the UC3825 oscillator and duty-control loop, wire the U2 gate-driver stage to J1, then review the completed connections. After the schematic is complete, the natural next stage is PCB layout: board sizing, stackup, and component placement. I can continue with that once execution is available again.
