PRELIMINARY
3+2 Voltage Regulator for IMVP-7/VR12™ CPUs
ISL95836
Features
Compliant with IMVP-7/VR12™, the ISL95836 provides a
• Serial Data Bus
complete solution for microprocessor and graphic processor
• Dual Outputs:
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 VR could
be configured as 2- or 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.
PRELIMINARYBased on Intersil’s Robust Ripple Regulator (R3) technology™,
- Configurable 3-, 2- or 1-phase for the 1st Output using 2
integrated Gate Drivers
- Configurable 2- or 1-phase for the 2nd Output using an
Integrated Gate Driver
• 0.5% System Accuracy Over-Temperature
• Supports Multiple Current Sensing Methods
- Lossless Inductor DCR Current Sensing
the PWM modulator compared to traditional modulators, has
- Precision Resistor Current Sensing
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.
CONFIDENTIALThe ISL95836 has several other key features. Both outputs
• Differential Remote Voltage Sensing
• Programmable VBOOT Voltage at Start-up
• Resistor Programmable IMAX, Switching Frequency for Both
support DCR current sensing with single NTC thermistor for
Outputs
DCR temperature compensation or accurate resistor current
sensing. Both outputs come with remote voltage sense,
programmable VBOOT voltage, IMAX and switching frequency,
IN REVIEWadjustable OC protection and separate Power-Good.
• Adaptive Body Diode Conduction Time Reduction

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil Pb-
free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL95836. For more information on MSL please see techbrief TB363.
