Single-Phase, Synchronous MOSFET Drivers  
/MAX8791B  
General Description  
Features  
The MAX8791/MAX8791B are single-phase, synchro-  
nous, noninverting MOSFET drivers. The MAX8791/  
MAX8791B are intended to work with controller ICs like  
the MAX8736 or MAX8786, in multiphase notebook  
CPU core regulators.

0.5Low-Side On-Resistance  
0.7High-Side On-Resistance  
8ns Propagation Delay  
The regulators can either step down directly from the  
battery voltage to create the core voltage, or step down  
from the main system supply. The single-stage conver-  
sion method allows the highest possible efficiency, while  
the 2-stage conversion at higher switching frequency  
provides the minimum possible physical size.  
15ns Minimum Guaranteed Dead Time  
Integrated Boost “Diode”  
2V to 24V Input Voltage Range  
Selectable Pulse-Skipping Mode  
Low-Profile TQFN Package  
The low-side drivers are optimized to drive 3nF capaci-  
tive loads with 4ns/8ns typical fall/rise times, and the  
high-side driver with 8ns/10ns typical fall/rise times.  
Adaptive dead-time control prevents shoot-through cur-  
rents and maximizes converter efficiency.  
The MAX8791/MAX8791B are available in a small, lead-  
free, 8-pin, 3mm x 3mm TQFN package.
