ISL95813单相控制器为英特尔微处理器提供了一个完全兼容VR12.6的电源解决方案。它还通过CPU的高速串行总线接口,提供了一个编程的,严格调控的输出电压。

The ISL95813 single-phase controller provides a fully compliant VR12.6 power supply solution for Intel™ microprocessors. It provides a tightly regulated output voltage that is programmed through a high speed serial bus interface with the CPU. This interface also allows the CPU to acquire real-time information from the voltage regulator (VR), which includes load current and VR temperature.

Based on Intersil’s Robust Ripple Regulator (R3™) technology, the PWM modulator provides faster transient response and settling time when compared against traditional modulation schemes. Its variable frequency topology also allows for natural period stretching discontinuous conduction mode (DCM) for increased efficiency and power savings in light load situations.

The ISL95813 has several other key features that include: DCR current sensing with single NTC thermal compensation; discrete resistor current sensing; differential remote voltage feedback; and user-programmable boot voltage, IMAX, TMAX, voltage transition slew rate, and switching frequency.

Full VR12.6 specification compliance Wide input voltage range: 4.6V to 25V R3™ control architecture delivers excellent transient response and power state mode transitions Current monitor (IMON) with temperature compensation VRHOT# indicator for CPU protection Digitally selectable switching frequency: 425kHz, 550kHz, 700kHz with ECO and PRO options Enhanced light-load efficiency discontinuous conduction mode operation Ultra-small 20 lead 3mmx4mm QFN package Enable and power-good monitor
