Single-Phase Synchronous MOSFET Driver  
MAX7491  
General Description  
Features  
The MAX17491 is a single-phase synchronous nonin-  
verting MOSFET driver. The MAX17491 is intended to  
work with controller ICs like the MAX8736, MAX8786, or  
MAX17030 in multiphase notebook CPU core regulators.  
Single-Phase Synchronous MOSFET Driver  
0.5Ω Low-Side On-Resistance  
0.7Ω High-Side On-Resistance  
10ns Minimum Guaranteed Dead Time  
Integrated Boost “Diode”  
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.  
2V to 24V Input Voltage Range  
Selectable Pulse-Skipping Mode  
Low-Profile, 3mm x 3mm, TQFN Package  
The low-side driver is optimized to drive 3nF capacitive  
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.  
Ordering Information  
The MAX17491 features improved zero crossing and  
UVLO performance over the MAX8791/MAX8791B.
