Microprocessor CORE Voltage Regulator
Multi-Phase Buck PWM Controller
The HIP6311A Multi-Phase Buck PWM control IC together
with HIP6601A, HIP6602A or HIP6603A companion gate
drivers form a precision voltage regulation system for
advanced microprocessors. The HIP6311A controls
microprocessor core voltage regulation by driving 2 to 4
synchronous-rectified buck channels in parallel. The multi-
phase buck topology takes advantage of interleaving phases
to increase ripple frequency and reduce input and output
ripple currents. Resulting in fewer components, reduced
component ratings, lower power dissipation, and smaller
implementation area.
The HIP6311A control IC features a 5 bit digital-to-analog
converter (DAC) that adjusts the core output voltage from
1.100V to 1.850V with an unsurpassed system accuracy of
±0.5% over temperature. The HIP6311A uses a lossless
current sensing approach in which the voltage developed
across the on-resistance of the lower MOSFETs during
conduction is sampled. Current sensing provides the
required signals for precision droop, channel-current
balancing, load sharing, and over-current protection.
Another feature of this control IC is the PGOOD monitor
which is held low until the core voltage increases to within
8% of the programmed voltage. An over-voltage condition is
detected when the output voltage exceeds 115% of the
programmed VID. This results in the converter shutting down
and PGOOD being pulled low. During an under-voltage
condition (output voltage 10% below the programmed VID),
PGOOD transitions low, but the converter continues to
operate.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is 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-020B.
