NCP4305DR2G (onsemi) Shortage Analysis onsemi SOIC8 synchronous rectifier driver IC, classic secondary-side solution for 100W PD chargers. Surging demand for high-density GaN adapters, slow expansion of analog wafer capacity lead to lead time over 20 weeks. Many charger manufacturers face risk of production halt due to material shortage.

Authorized Alternatives Recommendation Domestic direct substitutes: Maxic, Richtek RT synchronous rectifier IC, fully compatible with charger circuit design, pin-to-pin replacement available.
