BD9413F
針對升壓型單頻道大面板幕的白光LED驅動器
BD9413F是白光LED用高效率驅動器,適用於大型面板液晶驅動器。BD9413F內建了針對光源(LED串聯連接的陣列)提供適當電壓的DC/DC轉換器。BD9413F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。
