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 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 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 I_MAX, T_MAX, adjustable switching frequency, OC protection and separate

Power-Good.
