1 Features

  • Integrated synchronous rectifier FET and driver: 0.27mΩ
  • Operates from 5V external bias supply
  • Dead-time compensation (DTC) works with digital power controllers:
    • Automatic or manual dead-time adjustment of gate turn-on edges
  • Ideal diode mode (IDM) for autonomous turn-on edge optimization by sensing 3rd quadrant conduction
  • body-diode conduction sensing threshold: –250mV
  • Detection times of body diode conduction: as low as 4ns
  • High frequency operation: up to 5MHz
  • VCC undervoltage lockout (UVLO)
  • 3.3V or 5V input logic levels, 3.3V output logic level
  • 5mm × 6mm QFN package
    • Top-side exposed die for excellent thermal path top side
    • Large thermal pads for low thermal resistance bottom side
    • Large drain and source pads and corner pins for improved board level reliability (BLR) performance
