Descrizione

Traduzione AI

BD9489F is a high-efficiency white LED driver for large-size LCD panels. The device integrates a boost DC-DC converter and uses LED arrays as the light source. It features multiple fault protection functions, including overvoltage protection, DC-DC overcurrent limiting protection, LED overcurrent protection, and over-boost protection. As a result, it is well-suited for fail-safe designs across a wide output voltage range.
