7V, 7A SynchroFET™ Complementary
Drive Synchronous Half-Bridge
Designed with the Pentium® in mind, the Intersil SynchroFET
family provides a new approach f or 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 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 operatesincontinuousconduction mode reducing
EMI constraints and enabling high bandwidth operation.
Severalfeaturesensure easy start-up. First, the supply currents
stay below specification as the supply voltages r amp up; no
unexpected surges occur that might perturb a soft-start or
deplete a charge-pump. Second, any power-up sequence of
the V
currents. Third, the chip operates when V
so V
, VIN, or PWM pins can be used without causing large
CC
can be createdfrom a charge pump powered fromVIN.
