7V, 7A SynchroFET™ Complementary
Drive Synchronous Half-Bridge
Features
• Complementary Drive, Half-Bridge Power NMOS
• Use With Low-Cost Single-Output PWM Controllers
Designed with the Pentium® in mind, the Intersil SynchroFET
family provides a new approach for implementing a
• Improve Efficiency Over Conventional Buck Converter with
Schottky Clamp
synchronous rectified buck switching regulator. The
SynchroFET™ replaces two power DMOSs, a Schottky diode,
two gate drivers and synchronous control circuitry. The
complementary drive circuit turns the upper FET on and the
lower FET off when the input from the PWM is high. When the
input from the PWM goes low the upper FET turns off and the
lower FET turns on. The HIP5016 has a PWM pin that inverts
the relationship from the input to PHASE. This architecture
allows the designer to utilize a low cost single-ended PWM
controller in either a current or voltage mode configuration. The
SynchroFET operates in continuous conduction mode reducing
EMI constraints and enabling high bandwidth operation.
Several features ensure easy start-up. First, the supply currents
stay below specification as the supply voltages ramp up; no
unexpected surges occur that might perturb a soft-start or
deplete a charge-pump. Second, any power-up sequence of
• 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
the V , V , or PWM pins can be used without causing large

currents. Third, the chip operates when V is greater than 2V
CC
so V can be created from a charge pump powered from V .
• Bus Terminations (BTL and GTL)
• Drive 5V Motors Directly from Microprocessor
