Single-Phase Synchronous MOSFET Driver

The MAX8791 is a single-phase synchronous nonin- verting 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 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 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.
