製品概要

概要

SRK1004コントローラは、アクティブ･クランプ･フライバック、共振フライバック、および擬似共振フライバック･コンバータで2次側同期整流（SR）を行えるように設計されています。

本コントローラは、Nチャネル･ロジック･レベルまたは標準レベルのパワーMOSFETに適したゲート･ドライブ出力です。

本デバイスの制御スキームでは、電流がボディ･ダイオードを流れ始めるとすぐにSR MOSFETのスイッチがオンになり、電流がゼロに近づくとオフになります。

本デバイスには、ローサイド設定で動作時、コンバータの出力電圧から直接IC電源を供給できます。ハイサイド設定で使用する場合は、専用補助巻線コイルからICに電源を供給することをお勧めします。

ハイサイド設定で操作する場合は、アプリケーション専用機能を使用することで、ICが出力電圧から直接電源を得ているかのように動作し、短絡状態を素早く検出して異常を防ぎます。

特徴
アクティブ･クランプ･フライバック･コンバータ（NC-ACF）用に最適な2次側同期整流コントローラ。

ローサイド設定およびハイサイド設定の両方で動作可能

ロジック･レベル（AおよびB）と標準レベル（CおよびD）のMOSFETをサポート

広範囲のMOSFETに対応できる2種類のターンオフ遅延

広範な電源電圧範囲：4V～36V

非常に低い動作電流（580µA）と消費電流（230µA）

SR MOSFETドレイン･ソース電圧用の高電圧センシング入力（190V AMR）

動作周波数：最大500 kHz

高速短絡検出器

小型DFN 6L 2mm x 2mmパッケージ
