## Flyback Transformer Designer Description
Flyback Transformer Designer turns your flyback power supply spec into a complete transformer design — core, gap, turns, wire gauge, and loss breakdown — all computed locally on your device, no internet required.

Built for power-electronics engineers who need more than a spreadsheet. Covers all four operating modes: DCM, BCM, QR, and CCM. Supports multi-output secondaries with independent winding design, not a simplified single-output approximation.

Three steps to a finished design:
1. Enter your spec — Vin range, output voltages, power, frequency, and design constraints.
2. Review the top 5 core candidates — gap, Lm, winding layout, wire selection, copper/core losses, and temperature-rise estimates; switch the ranking between balanced, high-reliability, or lowest-loss.
3. Export a professional summary report (PDF or JSON).

Why you'll like it:
- Full core × turns × wire-gauge iteration with built-in AP pre-screening — no more flipping through datasheets by hand.
- Optional B_max design ceiling — leave it blank and the engine guards against saturation automatically using the material's Bsat×70% margin, so an overly conservative guess won't rule out viable designs; set your own ceiling anytime for an extra constraint.
- Built-in ferrite core library (EE, RM, PQ, ETD, etc.) plus My Database for your own materials, cores, and bobbins.
- Parameter sweep — explore f_sw, load, and Vin sensitivity curves before you wind a single turn.
- 100% local computation; your data never leaves your device.
- Native support for iPhone, iPad, and Mac (Apple silicon); switch between Chinese and English.

3-day full-feature trial from first launch — you are not charged when it ends. After the trial, a one-time App Store purchase unlocks steps 2–3, My Database editing, and export. This is not a subscription and does not auto-renew. Existing annual subscriptions remain valid until they expire.
