ISL6208CHRZ規(guī)格書詳情

The ISL6208C is a high frequency, dual MOSFET driver,

optimized to drive two N-Channel power MOSFETs in a

synchronous-rectified buck converter topology. It is especially

suited for mobile computing applications that require high

efficiency and excellent thermal performance. The driver,

combined with an Intersil multiphase Buck PWM controller,

forms a complete single-stage core-voltage regulator solution

for advanced mobile microprocessors.

The ISL6208C features 4A typical sinking current for the lower

gate driver. This current is capable of holding the lower

MOSFET gate off during the rising edge of the phase node. This

prevents shoot-through power loss caused by the high dv/dt of

phase voltages. The operating voltage matches the 30V

breakdown voltage of the MOSFETs commonly used in mobile

computer power supplies.

The ISL6208C also features a three-state PWM input that,

working together with Intersil’s multiphase PWM controllers,

will prevent negative voltage output during CPU shutdown. This

feature eliminates a protective Schottky diode usually seen in

microprocessor power systems.

MOSFET gates can be efficiently switched up to 2MHz using

the ISL6208C. Each driver is capable of driving a 3000pF load

with propagation delays of 8ns and transition times under

10ns. Bootstrapping is implemented with an internal Schottky

diode. This reduces system cost and complexity, while allowing

the use of higher performance MOSFETs. Adaptive

shoot-through protection is integrated to prevent both

MOSFETs from conducting simultaneously.

A diode emulation feature is integrated in the ISL6208C to

enhance converter efficiency at light load conditions. This

feature also allows for monotonic start-up into pre-biased

outputs. When diode emulation is enabled, the driver will allow

discontinuous conduction mode by detecting when the

inductor current reaches zero and subsequently turning off the

low-side MOSFET gate.
