Microprocessor CORE Voltage Regulator

Multi-Phase Buck PWM Controller

The HIP6302 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

phase converter configurations previously employed to

satisfy the ever increasing current demands of modern

microprocessors. Multi-phase convertors, 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

two phase convertor operating at 350kHz will have a ripple

frequency of 700kHz. Moreover, greater convertor 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 1.100V to 1.850V 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.
