4通道 150mA 恒流 LED 驅(qū)動器

RT8300 是4通道 150mA 恒流吸入式 LED 驅(qū)動器，4個通道間具有很好的電流一致性并容許很寬的 VF 變化范圍。 RT8300 的4個通道的電流差異在 3% 以內(nèi)，在不同芯片之間的誤差也是如此。沒個通道的電流可以通過一個外部電阻（ R_ISET )進(jìn)行調(diào)整，其范圍在 5mA~150mA 之間。LED 的亮度還可以通過在 PWMI 引腳施加占空比在 0%~100% 的 PWM 信號進(jìn)行調(diào)節(jié)。 RT8300 具有動態(tài)余量控制（ DHC ）功能，它能生成回饋信號送給 DC/DC 控制回路調(diào)節(jié)其供給 RT8300 的電壓。它還具有 LED 開路、 ? 4個恒流輸出通道\n? 低壓差：600mV@120mA\n? 動態(tài)余量控制（ DHC ）功能\n? OTP、LED 開路/短路故障檢測、指示\n? 符合 RoHS 規(guī)范，不含鹵素;
