ISL6564A
Data Sheet
March 20, 2007
FN6285.1
Multiphase PWM Controller with Linear
6-Bit DAC Capable of Precision r DS(ON) or
DCR Differential Current Sensing
The ISL6564A is a Multiphase PWM controller which controls
microprocessor core voltage regulation by driving up to
4 synchronous-rectified buck channels. It features a high
bandwidth control loop to provide optimal response to the load
transients. With switching frequency up to 1.5MHz per phase,
the ISL6564A based voltage regulator requires minimum
components and PCB area in DC/DC converter application.
The ISL6564A 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 their conduction intervals. Current sensing
provides the needed signals for precision droop, channel-
current balancing, and overcurrent protection.
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 ISL6564A 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. The ISL6564A
uses a 5V bias and has a built-in shunt regulator to allow
12V bias using only a small external limiting resistor.
