ISL6316
Data Sheet
December 12, 2006
FN9227.1
Enhanced 4-Phase PWM Controller with
6-Bit VID Code Capable of Precision
r DS(ON) or DCR Differential Current
Sensing for VR10 Application
The ISL6316 controls microprocessor core voltage regulation
by driving up to 4 synchronous-rectified buck channels in
parallel. Multiphase buck converter architecture uses
interleaved timing to multiply channel ripple frequency and
reduce input and output ripple currents. Lower ripple results in
fewer components, lower component cost, reduced power
dissipation, and smaller implementation area.
Microprocessor loads can generate load transients with
extremely fast edge rates. The ISL6316 features a high
bandwidth control loop and ripple frequencies up to >4MHz to
provide optimal response to the transients.
Today’s microprocessors require a tightly regulated output
voltage position versus load current (droop). The ISL6316
senses current by utilizing patented techniques to measure
the voltage across the on resistance, r DS(ON) , of the lower
MOSFETs or DCR of the output inductor during the lower
MOSFET conduction intervals. Current sensing provides the
needed signals for precision droop, channel-current
balancing, and overcurrent protection. A programmable
internal temperature compensation function is implemented to
effectively compensate for the temperature coefficient of the
current sense element.
A unity gain, differential amplifier is provided for remote
voltage sensing. Any potential difference between remote and
local grounds can be completely eliminated using the remote-
sense amplifier. Eliminating ground differences improves
regulation and protection accuracy. The threshold-sensitive
enable input is available to accurately coordinate the start up
of the ISL6316 with any other voltage rail. Dynamic-VID?
technology allows seamless on-the-fly VID changes. The
offset pin allows accurate voltage offset settings that are
independent of VID setting.
