Microprocessor CORE Voltage Regulator
Two-Phase Buck PWM Controller
The ISL6562 two-phase current mode, PWM control IC
together with companion gate drivers, the HIP6601A,
HIP6602A, HIP6603A or HIP6604 and MOSFETs provides a
precision voltage regulation system for advanced
microprocessors. Two-phase 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 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 converter operating at
350kHz per phase will have a ripple frequency of 700kHz.
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 1.050V to 1.825V with an accuracy of
±
0.8%.
Pull up currents on these VID pins eliminates the need for
external pull up resistors.
Another feature of this controller IC is the PWRGD monitor
circuit which is held low until the CORE voltage increases, to
within 18% of the programmed voltage. Over-voltage, 24%
above programmed CORE voltage, results in the PWRGD
output going low to indicate that the CORE is above the
specified limit. Under voltage is also detected and results in
PWRGD going low if the CORE voltage falls 18% below the
programmed level. Over-current protection folds back the
output voltage to 95mV, reducing the regulator dissipation.
These features provide monitoring and protection for the
microprocessor and power system.
