Overview

NCP5351 は、同期降圧コンバータのハイサイドとローサイドの両方のパワー MOSFET のゲートを駆動するように最適化された、デュアル MOSFET ゲートドライバです。 NCP5351 は、ゲートドライバを内蔵していない多相コントローラの優れたコンパニオンです。 このアーキテクチャにより、電源の設計者は MOSFET の近くにゲートドライバを配置して柔軟性を持たせることができます。4 A の駆動能力がある NCP5351 は、入力容量が大きい MOSFET のスイッチング損失の最小化に最適です。 最適化された内部適応型の非オーバーラップ回路は、両方の MOSFET が同じ状態ならないようにして、スイッチング損失をさらに低減します。

  • Synchronous Buck Converters
  • Power Supplies
  • 4 A Peak Drive Current
  • Rise and Fall Times < 15 ns typical into 6000 pF
  • Propagation delay from Inputs to Outputs < 20 ns
  • Adaptive NonOverlap Time Optimized for Large Power MOSFETs
  • Floating Top Driver Accommodates Applications Up to 25 V
  • Undervoltage Lockout to Prevent Switching when the Input Voltage is Low
  • Thermal Shutdown Protection Against Overtemperature
  • < 1.0 mA Quiescent Current - Enabled
  • 25 µA Quiescent Current - Disabled
  • Internal TG to DRN Pulldown Resistor Prevents HV Supply-Induced Turn On of High-Side MOSFET
