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