General Description
The FAN53418 is a high frequency, dual MOSFET driver
specifically designed to drive two power N-Channel
MOSFETs in a synchronous rectified buck converter.
These drivers combined with a FAN53168 Multi-Phase Buck
PWM controller and power MOSFETs form a complete core
voltage regulator solution for advanced microprocessors.
The FAN53418 drives both the upper and lower gates in a
synchronous rectifier to +12V. The upper gate drive imple-
ments bootstrapping with only an external capacitor and
diode required. This reduces implementation complexity
and allows the use of higher performance, cost effective,
N-Channel MOSFETs.
The output drivers in the FAN53418 have the capacity to
efficiently switch power MOSFETs at frequencies over
500kHz. Each driver is capable of driving a 3000pF load
with a ~20ns propagation delay and ~30ns transition time.
Adaptive shoot-through protection is integrated to prevent
both MOSFETs from conducting simultaneously. Addition-
ally an Output Disable function is included to synchronize
the driver with the PWM controller. The FAN53418 is
rated for operation from 0°C to +85°C and is available in a
low-cost SOIC-8 package.
