Description
描述
Compliant with IMVP-7/VR12?, the ISL95831 provides a complete solution for mICroprocessor and graphic processor core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be configured as 3-, 2- or 1-phase VR while the second output is 1-phase VR, providing maximum flexibility. The two VRs share the serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two-chip approach.
符合imvp-7 / VR12?，isl95831提供的微處理器和圖形處理器核心電源完整的解決方案。它提供了兩個穩(wěn)壓器（VRS）三集成的柵極驅動器。第一個VR可以配置為3 -，2 -或單相VR而第二輸出單相VR，提供最大的靈活性。兩VRS共享串行控制總線與CPU通信，實現(xiàn)更低的成本和更小的電路板面積與兩芯片的方法比較。
Based on Intersil’s Robust Ripple Regulator (R3) technology?, the PWM modulator compared to traditional modulators, has faster transient settling time, variable switching frequency during load transients and has improved light load efficiency with it’s ability to automatically change switching frequency.
基于Intersil的紋波穩(wěn)壓器（R3）技術?，PWM調制器相比，傳統(tǒng)的調制器，具有更快的瞬時沉降時間，可變開關頻率在負載瞬變期間提高了輕負載效率與它的自動改變開關頻率的能力。
The ISL95831 has several other key features. Both outputs support DCR current sensing with single NTC thermistor for DCR temperature compensation or accurate resistor current sensing. Both outputs come with remote voltage sense, programmable VBOOT voltage, programmable IMAX, TMAX, adjustable switching frequency, OC protection and separate Power-Good.
還有一些其他的isl95831關鍵特征。兩輸出支持DCR為DCR溫度補償或精密電阻電流傳感熱敏電阻NTC電流檢測單。兩輸出跟遠程電壓感應，可編程VBoot電壓，可編程的IMAX，Tmax，調節(jié)開關頻率，OC保護和單獨的電源良好。
