3+1 Voltage Regulator for IMVP-7/VR12™ CPUs FN7977 Rev 0.00 January 17, 2013 pliant with IMVP-7/VR12™, the ISL95831C provides a plete 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 municate with the CPU and achieve lower cost and smaller board area pared with the two-chip approach.
Based on Intersil’s Robust Ripple Regulator (R3) technology™, the PWM modulator pared 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.
