HIP5010, HIP5011 Data Sheet March 1996 File Number 4029.5 7V, 17A SynchroFET™ Complementary Drive Synchronous Half-Bridge Designed with the P6 and 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.
The complementary drive circuit turns the upper FET on and the lower FET off when the input from the
HIP5011 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 the VCC, VIN , or PWM pins can be used without causing large currents. Third
