Overview

NCP5005は高効率のブースト・コンバータで、PFMモードに基づいて電流ループで動作し、白色LEDを駆動します。電流モード・レギュレーションにより、LEDの輝度が一律になります。小型セラミック・キャパシタ向けに最適化されており、最大1.0 Wの出力電力を供給できます。

  • LEDディスプレイバックライト制御
  • キーボードバックライト
  • 高効率ステップアップコンバーター

  • 2.7 ～ 5.5 Vの入力電圧範囲
  • Voutが24V出力を許容することにより、5個直列にLEDを駆動可能
  • 過電圧保護内蔵
  • フルEMI 耐性
  • インダクタ・ベースのコンバータにより最大90%の効率を実現
  • 出力定電流制御
  • 0.3 µAスタンバイ低静止電流
  • 調光機能内蔵(PWM)
  • 低バッテリ電圧から直接駆動されるイネーブル機能
  • 自動LED電流マッチング
  • サーマルシャットダウン保護
  • すべてのピンはESD保護機能を内蔵
  • 低EMI放射

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
