Multiphase PWM Regulator for VR12™ Desktop CPUs
ISL6363
Fully compliant with VR12™ specifications, the ISL6363
provides a complete solution for microprocessor core and
graphics power supplies. It provides two Voltage Regulators
(VRs) with three integrated gate drivers. The first output (VR1)
can be configured as a 4, 3, 2 or 1-phase VR while the second
output (VR2) is a 1-phase VR. The two VRs share a serial control
bus to communicate with the CPU and achieve lower cost and
smaller board areacomparedwith a 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 its ability to automatically change switching frequency.
The ISL6363 has several other key features. Both outputs
support DCR current sensing with a single NTC thermistor for
DCR temperature compensation or accurate resistor current
sensing. Both outputs come with remote voltage sensing,
programmable VBOOT voltage, serial bus address, IMAX, TMAX,
adjustable switching frequency, OC protection and separate
power-good indicators. To reduce output capacitors, the
ISL6363 also has an additional compensation function for
PS1/2 mode and high frequency load transient compensation.
Features
