onsemi NCP5201
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).| Part No. | NCP5201 |
