Overview
MAX8791/MAX8791B 19-0628; Rev 2; 1/10 Single-Phase, Synchronous MOSFET Drivers General Description The MAX8791/MAX8791B are single-phase, synchronous, 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 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 drivers are 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/MAX8791B are available in a small, leadfree, 8-pin, 3mm x 3mm TQFN package.
