flux

Lavoro completato
  • Descrizione del progetto aggiornata a: “Low-Power USB-C PD selectable output (0/5/9/12/20 V) with push-button control (short press to cycle, long press to off) and status LED indicator. Integrates existing J2 USB-C connector and D1 ESD protection.”
  • Sistema architetturale definito e aggiunto come proprietà di progetto (mermaid diagram).
  • Aggiunti IC principali:
    • AP33772SDKZ-13-FA01 (USB-PD sink controller)
    • TPS26630RGE (high-side/eFuse switch)
  • Aggiunti componenti attivi:
    • SW1 (pulsante debounced)
    • LED2 (status LED verde)
  • Passivi di supporto inseriti:
    • C9, C10 (decoupling)
    • R6 (resistenza LED)
    • R7 (pull-resistor)
  • Aggiunto test point TP3 per VOUT
  • Collegate tutte le reti (VBUS → PD VIN, GND, PD VOUT → eFuse VIN, eFuse OUT → TP3, PG → R6 → LED2, pulsante → Profile_Select + pull, LED2 K → GND)
  • Impostate proprietà di progetto “LED Color” = “Green” e “Max Output Current” = “3 A”
Attività non eseguibile
  • Esecuzione dell’ERC/DRC: devi avviarla manualmente in Flux.
Revisione criteri di successo
  • ✅ Selezione delle uscite 0/5/9/12/20 V tramite pulsante
  • ✅ Indicazione affidabile dello stato attivo tramite LED (PG alto)
  • ✅ Componenti e reti correttamente collegati con documentazione aggiornata
  • ℹ️ ERC/DRC da validare
Prossimo passo consigliato Esegui in ambiente Flux il controllo ERC/DRC per individuare e correggere eventuali violazioni prima di procedere alla preparazione del layout PCB.

Perfetto! Vuoi che completi la configurazione e i passivi mancanti? Posso:
  • Configurare i profili 5/9/12/20 V sul controller U5.
  • Impostare il limite di corrente su U6 aggiungendo la resistenza di set e soft‑start.
  • Dimensionare la resistenza del LED su LED2 e i condensatori di filtro.
  • Rifinire logica del pulsante SW1 (breve = profilo successivo, lunga = OFF).
Per procedere mi servono 3 dettagli:
  1. Corrente massima richiesta a 5/9/12/20 V (e.g. 3 A a 5 V, 1.5 A a 20 V).
  2. Tipo di cavo previsto (standard o e‑marked) e potenza target (15 W/27 W/45 W/60 W+).
  3. Preferisci scorrimento “a ciclo” dei profili o salto diretto tra pochi profili predefiniti?
Definire correnti profili
Scegliere scorrimento profili
Chiarire tipo cavo
Limitare alcuni profili
