The MAX8791 is a single-phase synchronous noninverting
MOSFET driver. The MAX8791 is 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 conversion
method allows the highest possible efficiency, while
the 2-stage conversion at higher switching frequency
provides the minimum possible physical size.
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 currents and
maximizes converter efficiency.
The MAX8791 is available in a small, lead-free, 8-pin
3mm x 3mm TQFN package.
