18 通道 I2C 恒流 RGB LED 驅(qū)動(dòng)器

在智能家居以及配備人機(jī)交互功能的其他 應(yīng)用中， 高性能 RGB LED 驅(qū)動(dòng)器必不可少。LED 動(dòng)畫效果（如閃爍、呼吸以及追逐）可極大地改善用戶體驗(yàn)，同時(shí)最大限度地降低系統(tǒng)噪聲也至關(guān)重要。 \n\nLP50xx 器件是一款 18 或 24 通道恒定電流阱 LED 驅(qū)動(dòng)器。LP50xx 器件包含集成色彩混合和亮度控制，預(yù)配置特性簡(jiǎn)化了軟件編碼過(guò)程。為每個(gè)通道配備的集成式 12 位、29kHz PWM 發(fā)生器可實(shí)現(xiàn)流暢、清晰的 LED 色彩，并消除了可聞噪聲。\n\nLP50xx 以 12 位 PWM 分辨率和 29kHz 開關(guān)頻率控制每個(gè) LED 輸出，這有助于實(shí)現(xiàn)平滑的調(diào)光效果和消除可聞噪聲。 ? 工作電壓范圍： \n? VCC 范圍：2.7V 至 5.5V\n? 與 1.8V、3.3V 和 5V 電源軌兼容的 EN、SDA 和 SCL 引腳\n? 最大輸出電壓：6V\n \n? 24 路高精度恒定電流阱 \n? 在整個(gè) VCC 范圍內(nèi)，每個(gè)通道的最大電流為 25.5mA\n? 當(dāng) VCC ≥ 3.3V 時(shí)，每個(gè)通道的最大電流為 35mA\n? 器件間的誤差為 ±7%；通道間的誤差為 ±7%\n \n? 超低靜態(tài)電流： \n? 關(guān)斷模式：1μA（最大值），EN 處于低電平\n? 省電模式：10μA（典型），EN 處于高電平，所有 LED 關(guān)斷時(shí)間大于 30ms\n \;
