bir buck boost regülatör tasarlamak istiyorum bunun için izlememiz gereken yollar nelerdir.nasıl bir yol izleyerek kusursuz bir buck boost regülatör tasarlayabiliriz bu yolculukta senin istediğin veri var mı mesela şu şematiği bana yükle dediğin birşey var mı bu tasarımı yaparken dışardan ihtiyaç duyduğun herhangi bir veri varsa bu verilerin hepsini sana sağlayabilirim

Henüz projede şematik değişikliği yapılmadı; bileşen ve net sayısı 0. Şu anda ACU bulunmadığı için tasarımı doğrudan oluşturamıyorum.
Kusursuz bir buck-boost tasarımı için şu veriler gerekli:
  • Giriş gerilimi: nominal, minimum, maksimum ve transient değerleri
  • Çıkış gerilimi ve toleransı
  • Sürekli/tepe çıkış akımı
  • Yük profili: uyku, Wi‑Fi TX ve ani akım darbeleri
  • Verim, boşta akım ve ripple hedefleri
  • İzole veya izolesiz yapı
  • USB‑C yalnızca 5 V mu, yoksa USB‑PD de kullanılacak mı?
  • OVP/UVLO/OCP eşikleri, ters polarite ve kısa devre davranışı
  • Boyut, maliyet, sıcaklık aralığı ve PCB katman sınırları
  • Tercih edilen üretici/parça veya tedarik kısıtları
  • Varsa yükleyebileceğiniz mevcut şematik, blok diyagramı, BOM ve mekanik ölçüler
Bu proje USB‑C’den sabit 5 V alıp yalnızca 3.3 V üretecekse buck‑boost yerine düşük boşta akımlı bir buck regülatör genellikle daha verimli ve basit olur. Buck‑boost ancak girişin hedef çıkışın hem altına hem üstüne çıkması bekleniyorsa anlamlıdır. ACU yeniden kullanılabilir olduğunda önce güç bütçesini çıkarıp topolojiyi seçecek, ardından koruma katı, regülatör çevre elemanları, kararlılık/termal hesapları ve PCB yerleşimini doğrulayacağız.
