alles hat gepasst, > Footprints in Ordnung, Mir ist da mal was ähnliches passiert. Layot mit TL431B gemacht SOT-23-3 Footprint aus der Bibliothek Testplatine alles passt und Funktioniert. Dann Teile für die Serie bestellt. Wurden aber TS431BCX bestellt, waren halt viel günstiger, hatte bisher mit
auch. Es funktionierte aber nichts. Nanu im Test hat die Platine doch einwandfrei gearbeitet. Den 431 gegen einen noch rumliegenden TL getauscht, siehe da alles ging. Mit dem TS aber nicht. Studium der Datenblätter kam es dann, der TS431 hat eine andere Pinbelegung! Dort sind zum TL431 die Kathode und

regeln, Das kommt ja ungefähr hin. Ersetze den TL431 durch einen 680 Ohm Widerstand von A nach K (den kannst du auch einfach drauflöten ohne den TL431 zu entfernen) und vergiss die Einstellbarkeit.

Sind OC's bestimmter Typen oder Hersteller stärker betroffen? Es hängt größtenteils vom LED-Typ (GaAs, GaAlAs, GaAsP etc.) ab. Alle Hersteller behaupten, dass ihre LEDs langsamer altern als "herkömmliche LEDs". :-) Es gibt Hersteller, die dokumentieren die Alterung (z.B. https://docs.broadcom.com/docs
