Two/Three/Four-Phase Buck CPU Controller
NCP5318
Two/Three/Four−Phase
Buck CPU Controller
The NCP5318 provides full−featured and flexible control
conforming to the Intel® VRM 10.1 specification for
high−performance CPUs. The IC can be programmed as a two−,
three− or four−phase buck controller, and the per−phase switching
frequency can be as high as 1.0 MHz. Combined with external gate
drivers and power components, the controller implements a compact,
highly integrated multi−phase buck converter.
Enhanced V2 ™ control inherently compensates for variations in
both line and load, and achieves current sharing between phases. This
control scheme provides fast transient response, reducing the need for
large banks of output capacitors and higher switching frequency.
Features Switching Regulator Controller Programmable 2/3/4 Phase Operation Lossless Current Sensing Enhanced V2 Control Method Provides Fast Transient Response Programmable Up to 1.0 MHz Switching Frequency Per Phase Programmable Adaptive Voltage Positioning Programmable Soft−Start Time Current Sharing Differential Current Sense Pins for Each Phase Current Sharing Within 10% Between Phases Protection Features Programmable Latching Overcurrent Protection “111110” and “111111” DAC Code Fault Latched Overvoltage Protection Undervoltage Lockout External Enable Control Three−State MOSFET Driver Control through DRVON Signal System Power Management 6−Bit DAC with 0.5% Tolerance Compatible with VRM 10.1
