NCP5395

NCP5395 Product Preview 2/3/4-Phase Controller with On Board Gate Drivers for CPU Applications The NCP5395 provides up to a four−phase buck solution which combines differential voltage sensing, differential phase current sensing, adaptive voltage positioning, and on board gate drivers. Dual−edge pulse−width modulation (PWM) combined with inductor current sensing reduces system cost by providing the fastest initial response to dynamic load events. Dual−edge multiphase modulation reduces the total bulk and ceramic output capacitance required to meet transient regulation specifications. The on board gate drivers includes adaptive non overlap and power saving operation. A high performance operational error amplifier is provided to simplify compensation of the system. Patented Dynamic Reference Injection further simplifies loop compensation by eliminating the need to compromise between closed−loop transient response and Dynamic VID performance. Features Meets Intel’s VR11.1 Specifications Meets AMD 6 Bit Code Specifications Dual−edge PWM for Fastest Initial Response to Transient Loading High Performance Operational Error Amplifier Internal Soft Start Dynamic Reference Injection (Patent #US07057381) DAC Range from 0.5 V to 1.6 V DAC Feed Forward Function (Patient Pending) ±0.5% DAC Voltage Accuracy from 1.0 V to 1.6 V True Differential Remote Voltage Sensing Amplifier Phase−to−Phase Current Balancing “Lossless” Differential Inductor Current Sensing Differ...
