Single-Phase, Synchronous MOSFET Drivers
General Description
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.
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.
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.
