中型、大型LCD背光用白色LED驅(qū)動器

BD9470AFM是白色LED用高效率驅(qū)動器，適用于大屏幕液晶驅(qū)動器。BD9470AFM內(nèi)置了可向光源（LED串聯(lián)連接的陣列）提供適當(dāng)電壓的DCDC轉(zhuǎn)換器。BD9470AFM內(nèi)置了過電壓保護(hù)（OVP: over voltage protection）、過電流檢測（OCP: over current limit protection of DCDC）、短路電路保護(hù)（SCP: short circuit protection）、開路保護(hù)（open detection of LED string）等針對異常狀態(tài)的保護(hù)功能。因此，可在更寬的輸出電壓條件及負(fù)載條件下使用。 · 6chLED constantcurrent driver\n · LED maximum output current 250mA\n · Individual PWM dimming modulation allowed for LEDs\n · ±2%LED current accuracy (when eachLED is set to 130mA)\n · Built-inLED feedback voltage automatic adjustment circuit according toLED current \n · Built-in start-up circ;
