7V, 17A SynchroFET™ Complementary
Drive Synchronous Half-Bridge
Designed with the P6 and Pentium® in mind, the Intersil
SynchroFET™ family provides a new approach f or
implementing a synchronous rectified buck switchingregulator.
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 HIP5011 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 acurrentorvoltage mode configuration. The
SynchroFET operates in continuous conduction mode reducing
EMI constraints and enabling high bandwidth operation.
Severalfeaturesensureeasy 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 created from a charge pump powered from VIN.
