MAX8550, MAX8551 Datasheet (Maxim Integrated Products) - Integrated DDR Power-Supply Solutions

MAX8550, MAX8551, Integrated DDR Power-Supply Solutions

The MAX8550/MAX8551 integrate 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

MAX8550 Features

* make the MAX8550/MAX8551 ideally suited for DDR memory applications in desktops, notebooks, and graphic cards. The PWM controller in the MAX8550/MAX8551 utilizes Maxim’s proprietary Quick-PWM™ architecture with programmable switching frequencies of up to 600kHz. This control scheme handles wide inpu
