Overview
EVALUATION KIT AVAILABLE MAX17000 Complete DDR2 and DDR3 Memory Power-Management Solution General Description The MAX17000 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 the required VDDQ, VTT, and VTTR rails.
The VDDQ rail is supplied by a step-down converter using Maxim’s proprietary Quick-PWM™ controller.
The high-efficiency, constant-on-time PWM controller handles wide input/output voltage ratios (low duty-cycle applications) with ease and provides 100ns response to load transients while maintaining a relatively constant switching frequency.
The Quick-PWM architecture circumvents the poor load-transient timing problems of fixed-frequency current-mode PWMs while also avoiding the problems caused by widely varying switching frequencies in conventional constant-on-time and constant-off-time PWM schemes.
The controller senses the current to achieve an accurate valley current-limit protection.
It is also built in with overvoltage, undervoltage, and thermal protections.
The MAX17000 can be set to run in three different modes: power-efficient SKIP mode, low-noise forced-PWM mode, and standby mode to support memory in notebook computer standby operation.
The switching frequency is programmable from 200kHz to 600kHz to allow small components and high efficiency.
The VDDQ output voltage can be set to a preset 1.
8V or 1.
5V, or be adjusted from 1.
0V to 2.
5V by an external resistor-divider.
This output has 1% accuracy over line-and-load operating range.
The MAX17000 includes a ±2A source/sink LDO regulator for the memory termination VTT rail.
This VTT regulator has a ±5mV deadband that either sources or sinks, ideal for the fast-changing load burst present in memory termination applications.
This feature also reduces output capacitance requirements.
The VTTR reference buffer sources and sinks ±3mA, providin...
