BD9411F
升壓型單通道 針對大螢幕的白色LED驅動器

BD9411F是白色LED用高效率驅動器,適用於大螢幕液晶驅動器。BD9411F內建了可向光源(LED串聯連接的陣列)提供適當電壓的DC/DC轉換器。BD9411F中內建了應對異常狀態的幾種保護功能。過電壓保護(OVP: over voltage protection), 過電流檢測(OCP: over current limit protection of DC/DC), LED 過電流保護(LEDOCP: LED over current protection), 過升壓保護(FBMAX: over boost protection)等。因此,可在更寬的輸出電壓條件及負載條件下使用。
