MAX8632ETI+T - Maxim Integrated Function Overview

The MAX8632ETI+T is an integrated DDR power-supply solution for desktops, notebooks and graphic cards in 28 pin TQFN package. It integrates a synchronous-buck PWM controller to generate VDDQ, a sourcing and sinking LDO linear regulator to generate VTT and a 10mA reference output buffer to generate VTTR. The buck controller drives two external N-channel MOSFETs to generate output voltages down to 0.7V from a 2V to 28V input with output currents up to 15A. The LDO can sink or source up to 1.5A continuous and 3A peak current. Both LDO output and 10mA reference buffer output can be made to track REFIN voltage. This feature make device ideally suited for DDR memory applications in desktops, notebooks and graphic cards. The PWM controller in device utilizes Quick-PWM architecture with programmable switching frequencies of up to 600KHz. It offers fully programmable UVP/OVP and skip-mode options ideal in portable applications and skip mode allows for improved efficiency at lighter loads.
