HIP6303
Microprocessor CORE Voltage Regulator
Multi-Phase Buck PWM Controller
The HIP6303 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 microprocessors.
Multiphase power conversion is a marked departure from
earlier single channel converter configurations previously
employed to satisfy the ever increasing current demands of
modern microprocessors. Multi-phase converters, by
distributing the power and load current results 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 three channel converter operating at 350kHz will
have a ripple frequency of 1.05MHz. Moreover, greater
converter bandwidth of this design results in faster response
to load transients.
Outstanding features of this controller IC include
programmable VID codes from the microprocessor that
range from 1.30V to 2.05V with a system accuracy of
±
1%.
Pull up currents on these VID pins eliminates the need for
external pull up resistors. In addition “droop” compensation,
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 within 10% of the
programmed voltage. Over-voltage, 15% above programmed
CORE voltage, results in the converter shutting down and
turning the lower MOSFETs ON to clamp and protect the
microprocessor. Under voltage is also detected and results
in PGOOD low if the CORE voltage falls 10% below the
programmed level. Over-current protection reduces the
regulator current to less than 25% of the programmed trip
value. These features provide monitoring and protection for
the microprocessor and power system.
