MAX17000AETG+T

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.
