19-5324; Rev 0; 6/10 www.DataSheet4U.com KIT ATION EVALU E L B AVAILA Single-Phase Synchronous MOSFET Driver General Description The MAX17491 is a single-phase synchronous noninverting MOSFET driver. The MAX17491 is intended to work with controller ICs like the MAX8736, MAX8786, or MAX17030 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.
