ISL6556B
Optimized Multi-Phase PWM Controller
with 6-Bit DAC and Programmable Internal
Temperature Compensation for VR10.X
Application
The ISL6556B controls microprocessor core voltage
regulation by driving up to 4 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 ISL6556B utilizes r
DS(ON)
current sensing in each
phase 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 nullify the effect of
r
DS(ON)
temperature sensitivity.
A unity gain, differential amplifier is provided for remote voltage
sensing. Any potential difference between remote and local
grounds can be eliminated using the remote-sense amplifier.
The precision threshold-sensitive enable input is available to
accurately coordinate the startup of the ISL6556B with Intersil
MOSFET driver IC. 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
ISL6556B uses 5V bias and has a built-in shunt regulator to
allow 12V bias using only a small external limiting resistor.
