BD9416FS
升壓型雙通道 針對大螢幕的白色LED驅動器

BD9416FS是白色LED用高效率驅動器,適用於大螢幕液晶驅動器。BD9416FS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。BD9416FS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(LEDOCP: LEDOver 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。
