ISL6565A, ISL6565B
Data Sheet
December 1, 2005
FN9135.4
Multi-Phase PWM Controller with
Precision r DS(ON) or DCR Current Sensing
for VR10.X Application
The ISL6565A, ISL6565B controls microprocessor core
voltage regulation by driving up to 3 synchronous-rectified
buck channels in parallel. Multi-phase buck converter
architecture uses interleaved timing to multiply channel
ripple frequency and reduce input and output ripple currents.
The difference between the ISL6565A and the ISL6565B is
that the ISL6565A utilizes r DS(ON) current sensing, while the
ISL6565B utilizes DCR current sensing for each phase.
These cost and space saving methods of current sensing
are used for adaptive voltage positioning (droop), channel-
current balancing, and overcurrent protection. To ensure the
accuracy of droop, a programmable internal temperature
compensation function is implemented to compensate the
effect of r DS(ON) and DCR temperature sensitivity.
A unity gain, differential amplifier is provided for remote
voltage sensing. Any potential difference between remote
and local grounds is eliminated using the remote-sense
amplifier. The precision threshold-sensitive enable input is
available to accurately coordinate the start up of the
ISL6565A, ISL6565B with Intersil MOSFET driver ICs.
Dynamic-VID? technology allows seamless on-the-fly VID
changes. The offset pin allows accurate voltage offset
settings that are independent of VID setting.
