ISL6571 Datasheet Complementary MOSFET Driver And Synchronous Half-bridge Switch

Manufacturer: Intersil (now Renesas)

Overview: ® ISL6571 Data Sheet February 2003 FN9082.2 plementary MOSFET Driver and Synchronous Half-Bridge Switch The Intersil ISL6571 provides a new approach for implementing a synchronous rectified buck switching regulator. The ISL6571 replaces two power MOSFETs, a Schottky diode, two gate drivers and synchronous control circuitry. Its main applications address high-density power conversion circuits including multiphase-topology puter microprocessor core power regulators, ASIC and memory array regulators, etc. Another useful feature of the ISL6571 is the patibility with three-state input control: left open, the PWM input turns off both output drives. The ISL6571 operates in continuous conduction mode reducing EMI constraints and enabling high bandwidth operation.

Key Features

  • Improved Performance over Conventional Synchronous Buck Converter using Discrete Components.
  • Optimal Deadtime Provided by Adaptive Shoot-Through.
  • Switching Frequency up to 1MHz - High-Bandwidth, Fast Transient Response - Small, Low Profile Converters.
  • Reduced Connection Parasitics between Discrete Components - Low Electromagnetic Emissions.
  • Low Profile, Low Thermal Impedance Packaging - High Power Density.
