ISL95836 Features The ISL95836 Pulse Width Modulation (PWM) controller IC
provides a complete solution for IMVP-7/VR12^TM 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. • Serial Data Bus
• Dual Outputs:
-Configurable 3-, 2-or 1-phase for the 1st Output Using Two
Integrated Gate Drivers
-Configurable 2-or 1-phase for the 2nd Output Using One
Integrated Gate Driver Both VRs utilize Intersil's Robust Ripple Regulator R3
Technology^TM. 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. • Supports Multiple Current Sensing Methods …
