Description
The ISL95836 Pulse Width Modulation (PWM) controller IC provides a complete solution for IMVP-7/VR12™ compliant
microprocessor and graphic processor core power supplies. It provides the control and protection for two Voltage
Regulators (VRs). The first VR, typical for Vcore, incorporates 2 integrated drivers and can operate in 3-, 2- or 1-phase
configurations. The second VR, typical for Graphics, incorporates 1 integrated driver and can operate in 2- or 1-phase
configurations. The two VRs share a serial control bus to communicate with the CPU and achieve lower cost and
smaller board area compared with the two-chip approach.
Both VRs utilize Intersils Robust Ripple Regulator R3 Technology™. The R3 modulator has numerous advantages
compared to traditional modulators, including faster transient response, variable switching frequency during load
transients, and improved light load efficiency due to its ability to automatically change switching frequency.
The ISL95836 has several other key features. Both outputs support either DCR current sensing with a single NTC
thermistor for DCR temperature compensation, or more precise resistor current sensing if desired. Both outputs come
with remote voltage sense, programmable V
