概要

TIDA-01234 は、LM3481-Q1 ベースの車載 LED アプリケーションに最適な、高効率(94%)、低コスト 24W 非同期整流昇圧回路のためのリファレンス・デザインです。
このリファレンス・デザインの用途は、ヘッドライトやリア・ライトなどの車載高輝度照明や、室内 LED 照明システムです。入力範囲 6Vin ~ 18Vin で動作し、1A の定電流で動作する 6 ~ 7 個の LED(16V ~ 24V)を直列接続したストリングを複数駆動することができます。このリファレンス・デザインは、アナログ LED 輝度制御と、出力開路の保護機能をサポートしています。バッテリ電圧までの昇圧を行う構成を採用する場合、LED ストリングで必要とされる電圧を基準として、入力電圧はそれより高くても、低くても、または等しくても問題はありません。

主な特長

  • 24W 車載 LED ドライバ・ソリューション
  • 昇圧構成の場合、12Vin、最大負荷時に 94% のシステム効率。バッテリ電圧までの昇圧構成の場合、12Vin、最大負荷時に 88.9% のシステム効率
  • 開路保護
  • スイッチング周波数:350kHz
