95831HRTZ - Intersi - QFN-48

3+1 Voltage Regulator for IMVP-7/VR12 CPUs

رگولاتور ولتاژ برای پردازنده

Description

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 twochip approach
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
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
