NCP5201

Dual Output

DDR Power Controller

The NCP5201 Dual DDR Power Controller is specifically

designed as a total power solution for a high current DDR memory

system. This IC combines the efficiency of a PWM controller for the

VDDQ supply with the simplicity of a linear regulator for the VTT

memory termination voltage. The secondary regulator (VTT) is

designed to automatically track at half the primary regulator voltage

(VDDQ). An internal power good voltage monitor tracks both

VDDQ and VTT outputs and notifies the user in the event of a fault

on either output. Protective features include soft−start circuitry and

undervoltage monitoring of VCC and VSTBY. The IC is packaged in

a 5 × 6 QFN−18.
