ISL6560
Microprocessor CORE Voltage Regulator
Two-Phase Buck PWM Controller
The ISL6560 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.
Higher converter bandwidth is also achievable, resulting in
faster response to load transients.
An outstanding feature of this controller IC includes high-
side current sensing with a single current sampling resistor
in the input line to the output MOSFET transistors. This
single current sampling resistor monitors each channels
input current assuring excellent current sharing. Current
mode control results in rapid response to changing load
demands.
Also featured are programmable VID codes with an accuracy
of
±
0.8% that range from 1.100–1.850V, and are set by the
microprocessor. 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 and load protection circuits which provide overvoltage
protection, overcurrent protection and undervoltage
indication.

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