針對升壓型單通道大螢幕的白色LED驅動器 - BD9408FV
BD9408FV是白色LED用高效率驅動器，適用於大螢幕液晶驅動器。BD9408FV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。BD9408FV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過流保護(LED OCP: LED Over Current Protection)、過升壓保護(FBMAX)等。因此，可在更寬的電壓條件及負載條件下使用。
