3 概要

LP5569デバイスはプログラム可能で使いやすい9チャネルのI2C LEDドライバで、各種のアプリケーションで照明効果を生み出すよう設計されています。LEDドライバには、ユーザーによりプログラムされたシーケンスを格納するSRAMメモリと、3つのプログラム可能なLEDエンジンが搭載されており、プロセッサの制御なしで動作可能です。自律的な動作により、プロセッサがスリープ・モードのときシステムの消費電力が削減されます。

高効率のチャージ・ポンプにより、2.5Vの入力電圧でも高いVFのLEDを駆動できます。LP5569 LEDドライバは、LEDの順方向電圧要件に基づいて最良のチャージ・ポンプのゲインを自律的に選択し、広い動作電圧範囲にわたって良好な効率を維持します。

LEDがアクティブでないとき、LP5569はパワーセーブ・モードへ移行し、アイドル消費電流を大幅に削減します。柔軟なデジタル・インターフェイスにより、同じシステム内で各デバイスに固有のI2Cスレーブ・アドレスを使用して、最大8つのLP5569デバイスを接続でき、すべてのデバイス間で照明効果を同期できます。
