Dual Bootstrapped 12 V MOSFET  
Driver with Output Disable  
ADP3118  
FEATURES  
GENERAL DESCRIPTION  
Optimized for low gate charge MOSFETs  
All-in-one synchronous buck driver  
Bootstrapped high-side drive  
One PWM signal generates both drives  
Anticross-conduction protection circuitry  
The ADP3118 is a dual high voltage MOSFET driver optimized  
for driving two N-channel MOSFETs, which are the two switches  
in a nonisolated synchronous buck power converter. Each of the  
drivers is capable of driving a 3000 pF load with a 25 ns  
propagation delay and a 25 ns transition time. One of the drivers  
can be bootstrapped and is designed to handle the high voltage  
slew rate associated with floating high-side gate drivers. The  
ADP3118 includes overlapping drive protection to prevent  
shoot-through current in the external MOSFETs.  
Output disable control turns off both MOSFETs  
to float output per Intel® VRM 10 specification  
APPLICATIONS  
Multiphase desktop CPU supplies  
Single-supply synchronous buck converters  
OD  
The  
pin shuts off both the high-side and the low-side  
MOSFETs to prevent rapid output capacitor discharge during  
system shutdown.  
The ADP3118 is specified over the commercial temperature  
range of 0°C to 85°C and is available in 8-lead SOIC package.
