Complementary MOSFET Driver and

Synchronous Half-Bridge Switch

The Intersil ISL6571 provides a new approach for

implementing a synchronous rectified buck switching

regulator. The ISL6571 replaces two power MOSFETs, a

Schottky diode, two gate drivers and synchronous control

circuitry. Its main applications address high-density power

conversion circuits including multiphase-topology computer

microprocessor core power regulators, ASIC and memory

array regulators, etc. Another useful feature of the ISL6571

is the compatibility with three-state input control: left open,

the PWM input turns off both output drives. The ISL6571

operates in continuous conduction mode reducing EMI

constraints and enabling high bandwidth operation.

*Add “-T” suffix for tape and reel.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which are RoHS compliant and compatible

with both SnPb and Pb-free soldering operations. Intersil Pb-free

products are MSL classified at Pb-free peak reflow temperatures that

meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
