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 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 a current or voltage mode configuration. The
SynchroFEToperatesincontinuousconductionmodereducing
EMI constraints and enabling high bandwidth operation.
Severalfeaturesensureeasystart-up.First,thesupplycurrents
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 V
CC
, V
IN
, or PWM pins can be used without causing large
currents. Third, the chip operates when V
CC
is greater than 2V
so V
CC
can be created from a charge pump powered from V
IN
.
