General Description
The FAN5009 is a dual, high frequency MOSFET driver,
speci?cally designed to drive N-Channel power MOSFETs
in a synchronous-recti?ed buck converter. These drivers,
combined with a Fairchild Multi-Phase PWM controller and
power MOSFETs, form a complete core voltage regulator
solution for advanced microprocessors.
The FAN5009 drives the upper and lower MOSFET gates of
a synchronous buck regulator to 12VGS. The upper gate
drive includes an integrated boot diode and requires only an
external bootstrap capacitor (CBOOT). The output drivers in
the FAN5009 have the capacity to ef?ciently switch power
MOSFETs at frequencies up to 500kHz. The circuit’s
adaptive shoot-through protection prevents the MOSFETs
from conducting simultaneously.
The FAN5009 is rated for operation from 0°C to +85°C and
is available in low-cost SOIC-8 or MLP packages.
