I will evaluate your power supply circuit before you build the pcb
Engineering on demand from PCB schematics to API review
About this Gig
Catch power supply problems on screen before you spend money on a board spin.
If your product has a switching regulator or LDO and you're not sure it will be stable, efficient, or quiet enough, I simulate the circuit and tell you what will actually happen once it's built - while it's still cheap to change.
Good for startups and small teams who have a design but no in-house power electronics expertise.
What you get:
- Startup, output ripple and load-step behaviour, simulated in LTspice
- Efficiency estimate with a breakdown of where the losses go- Loop stability check (Bode plot: crossover frequency and phase margin)
- Real component parasitics modelled (DCR, ESR), not ideal parts
- A clear PDF report: what's fine, what's risky, what to change
Works with buck, boost, buck-boost, LDOs and filter networks. I use the real regulator IC model where the vendor provides one and clearly flag any assumptions where they don't.
Send me your schematic or a rough spec before ordering and I'll tell youhonestly what I can do with it.

FAQ
Do you need a special file for my regulator chip?
If the manufacturer publishes a SPICE model for your IC, I use it. If they don't, I model the controller's behaviour instead and clearly mark that part as an approximation.
Can you simulate a circuit I didn't design myself?
Yes. Send whatever you have: a schematic, a PDF, even a clear hand sketch with component values... and I'll rebuild it for simulation.
What if there's no model available for my parts?
I substitute an equivalent circuit and flag every assumption I make. The results show you the right trends and problem areas, but won't be exact to the silicon.
Do I get the editable simulation file?
The Standard and Premium packages include the LTspice (.asc) file so you or your engineer can re-run it. Basic delivers the report only.
Do you deliver a PCB or Gerber files?
No: this service simulates and validates your circuit's behaviour. It doesn't include board layout, routing, or fabrication files.
