The MAX8553 is a 4.5V to 28V input-voltage, synchronous step-down controller that provides a complete power-management solution for DDR memory.
The MAX8553 generates 1/2 VREFIN voltage for VTT and VTTR.
The VTT and VTTR tracking voltages are maintained within 1% of 1/2 VREFIN.
The MAX8554 is a 4.5V to 28V input voltage, nontracking step-down controller with a low 0.6V feedback threshold voltage.
The MAX8553/MAX8554 use Maxim’s proprietary Quick-PWM™ architecture for fast transient response and operate with selectable pseudo-fixed frequencies. Both controllers can operate without an external bias supply.
