5V / 1A SMPS
An offline flyback prototype using a custom hand-wound RM10/I transformer and TNY285 controller, with schematics, BOMs, waveform captures and bench validation notes.

Power electronics
proven on the bench.
We support low-power converter prototypes from architecture through bench bring-up, using measured behavior to guide the next design decision.
This work is useful when switching behavior, component selection, transformer design or incomplete measurements are slowing the next revision.

Turn waveforms
into decisions.
Design and bring-up
- Converter architecture and low-power SMPS development
- Flyback topology and magnetics/transformer design support
- Component selection, snubbers and switching behavior
- PCB design review and prototype bring-up
- EMI considerations within the prototype scope
Measurement and validation
- Oscilloscope measurements and differential probing
- Electronic-load testing and LCR measurements
- Waveform review, bench notes and validation reporting
- High-voltage safety and validation where applicable
- Clear boundaries around energized hardware and test conditions

03Typical deliverables
Evidence for the
next revision.
- Converter architecture or component-selection notes
- Prototype schematics, BOM review or PCB observations
- Bring-up checklist and measured waveforms
- Electronic-load or component test observations
- Validation notes and prioritized next steps
The deliverables depend on the hardware, the measurements available and the scope we agree together.
04Representative work
A documented
SMPS prototype.
This is public technical work, not presented as a completed client contract or certified product.
05Engagement process
Measure what
matters next.
Technical discussion → Evidence and requirements review → Architecture or recovery plan → Implementation → Integration and validation → Documentation and handoff
The sequence changes with the voltage, topology, hardware access, safety requirements and project scope.
06Good fit
Start with the
measured question.
- Low-power converter prototype review
- Flyback bring-up and waveform investigation
- Component, magnetics or snubber questions
- Bench validation and documentation of an existing prototype
Not a fit: unsafe or unlawful work, requests requiring certification this practice does not provide, mass-production commitments, or energized hardware without suitable access and controls.
