Product 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.
  • Supply voltage range is 2V to 28V, up to 600KHz selectable switching frequency
  • Operating temperature range from -40°C to 85°C, 1.8V/2.5V fixed or 0.7V to 5.5V adjustable output
  • Quick-PWM with 100ns load-step response, up to 95% efficiency
  • Programmable current limit with foldback capability, 1.7ms digital soft-start
  • Independent shutdown and standby controls, overvoltage/ undervoltage protection option
  • Power-good window comparator LDO section, fully integrated VTT and VTTR capability
  • VTT Has ±3A sourcing/sinking capability
  • VTT and VTTR outputs track VREFIN/2
  • Only 20µF ceramic capacitance required for VTT
  • All ceramic output capacitor designs
