HIP5015, HIP5016 Data Sheet June 1996 7V, 7A SynchroFETTM Complementary Drive Synchronous Half-Bridge Designed with the Pentium(R) in mind, the Intersil SynchroFET family provides a new approach for implementing a synchronous rectified buck switching regulator. The SynchroFETTM 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 the VCC, VIN, or PWM pins can be used without causing large currents. Third, the chip operates when VCC is greater than 2V so VCC can be created from a charge pump powered from VIN. TEMP.
