Personal / public technical prototype

5 V / 1 A
SMPS.

An offline flyback prototype documented from transformer winding and component selection through waveform capture and bench validation.

FLYBACKTNY285MAGNETICSWAVEFORMSVALIDATION

01 / Objective

Turn a power stage
into evidence.

The project follows an offline flyback prototype through transformer and component decisions, schematics or BOM material, waveform capture and bench validation notes.

This is a personal public prototype. It is not presented as a certified supply, production design, commercial deployment or guaranteed output result.

02 / Scope

Magnetics,
switching, tests.

Technical scope

The repository provides a traceable record of transformer work, component selection, schematic/BOM material, captured switching waveforms and bench observations.

Topology

Offline flyback prototype.

Validation

Bench measurements and waveform review.
