Description
Compliant with IMVP-7/VR12™, the ISL95835 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.
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 ISL95835 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,

The ISL95837 can be considered as ISL95835 dedicated for 1+1 application. VR1 and VR2 are both 1-phase VR.
