7V, 7A SynchroFET™ Complementary Drive Synchronous Half-Bridge

Designed with the Pentium® in mind, the Intersil SynchroFET family provides a new approach for implementing a synchronous rectified buck switching regulator. The SynchroFET™ replaces two power DMOSs, a Schottky diode, two gate drivers and synchronous control circuitry.

Features

• Complementary Drive, Half-Bridge Power NMOS

• Use With Low-Cost Single-Output PWM Controllers

• Improve Efficiency Over Conventional Buck Converter with Schottky Clamp

• Minimum Deadtime Provided by Adaptive Shoot-Through Protection Eliminates External Schottky

• Grounded Case for Low EMI and Simple Heatsinking

• Low Operating Current

• Frequency Exceeding 1MHz

• Dual Polarity Input Options

• All Pins Surge Protected

Applications

• 5V to ≤3.3V Synchronous Buck Converters

• 3.3V to ≤2.9V Synchronous Buck Converters

• Pentium Power Supplies

• Bus Terminations (BTL and GTL)

• Drive 5V Motors Directly from Microprocessor
