Product Overview

The MAX17000AETG+T is a complete DDR2 and DDR3 memory power management solution in 24 pin TQFN package. This pulse width modulation (PWM) controller provides a complete power solution for notebook DDR, DDR2 and DDR3 memory. It comprises a stepdown controller, a source-sink LDO regulator and a reference buffer to generate required VDDQ, VTT and VTTR rails. VDDQ rail is supplied by a step down converter using Maxim's Quick-PWM controller. The high efficiency, constant on time PWM controller handles wide input/output voltage ratios with ease and provides 100ns response to load transients while maintaining a relatively constant switching frequency. It includes a ±2A source sink LDO regulator for memory termination VTT rail. This VTT regulator has a ±5mV dead band that either sources or sinks, ideal for the fast changing load burst present in memory termination applications. It is used in notebook computers and SSTL memory supplies.
  • Supply voltage range is 4.5V to 5.5V
  • Operating temperature range of -40°C to 85°C, o/p voltage preset 1.8V, 1.5V or adjustable 1V to 2.5V
  • SMPS regulator (VDDQ), quick-PWM with 100ns load-step response
  • 1% VOUT accuracy over line and load, 26V maximum input voltage rating
  • Accurate valley current-limit protection, 200KHz to 600KHz switching frequency
  • Source/sink linear regulator (VTT), ±2A peak source/sink, low output capacitance requirement
  • Output voltages preset VDDQ/2 or REFIN adjustable from 0.5V to 1.5V
  • Soft-start/soft-shutdown, SMPS power good window comparator
  • VTT power good window comparator, selectable overvoltage protection
  • Undervoltage/thermal protections, ±3mA reference buffer (VTTR)
