Controller
The ISL6223 multi-phase PWM control IC together with its
companion gate drivers, the HIP6601, HIP6602 or HIP6603
and Intersil MOSFETs provides a precision voltage
regulation system for advanced mobile microprocessors. A
single-stage regulator that directly converts a battery voltage
to a microprocessor core voltage can be designed when high
voltage drivers are employed. Multiphase power conversion
is a marked departure from earlier single phase converter
configurations previously employed to satisfy the ever
increasing current demands of modern microprocessors.
Multi-phase converters, by distributing the power and load
current, result in smaller and lower cost transistors with
fewer input and output capacitors. These reductions accrue
from the higher effective conversion frequency with higher
frequency ripple current due to the phase interleaving
process of this topology. For example, a two phase converter
operating at 350kHz will have a ripple frequency of 700kHz.
Moreover, greater converter bandwidth of this design results

used to reduce the overshoot or undershoot of the CORE
voltage, is easily programmed with a single resistor.
Another feature of this controller IC is the PGOOD monitor
circuit which is held low until the CORE voltage increases,
during its Soft-Start sequence, to 0.9V. Overvoltage, the
CORE voltage going above 2.35V, results in the converter
shutting down and turning the lower MOSFETs ON to clamp
and protect the microprocessor. Under voltage is also

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.
detected and results in PGOOD low if the CORE voltage
falls below 0.9V. Overcurrent protection reduces the
regulator current to less than 25% of the programmed trip
value. An external capacitor connected to the DACOUT pin
and ground slows down the transition of the DAC output to
avoid triggering the overcurrent protection when the VID
code changes. These features provide monitoring and
protection for the microprocessor and power system.
