General Description
The FAN5109 is a high-frequency driver, specifically
designed to drive N-Channel power MOSFETs in a syn-
chronous-rectified buck converter. This driver, combined
with a Fairchild Multi-Phase PWM controller and power
MOSFETs, form a complete core voltage regulator solu-
tion for advanced microprocessors.
The FAN5109 drives the upper and lower MOSFET gates
of a synchronous buck regulator up to 12V
FAN5109’s output drivers can efficiently switch power
MOSFETs at frequencies above 500kHz. The circuit’s
adaptive shoot-through protection prevents the MOSFETs
from conducting simultaneously.
GS
. The
The FAN5109 is rated for operation from 0°C to +85°C
and is available in a low-cost SOIC-8 package.
