Apr 15, 2014 Advanced Linear EAPP Digital 6-Phase Green PWM Controller for Digital Power
Management With NVM and AUTO Phase Shedding
The ISL6388 is a smart and smallest 6-Phase Green PWM
controller, designed to be compliant to Intel VR12.5/VR12
specifications and control the microprocessor core or memory
voltage regulator. It includes programmable functions and
telemetries for easy use, system flexibility and over-clocking
applications using SMBus, PMBus, or I2C interface, which is
designed to be conflict free with CPU’s SVID bus and to
program NVM banks up to 8 different compensations and
system parameters. This minimizes external components and
significantly reduces design complexity and PCB area, and
simplifies the manufacturing process.
The ISL6388 utilizes Intersil’s proprietary Advanced Linear EAPP
(Enhanced Active Pulse Positioning) Digital control scheme to
achieve the extremely fast linear transient response with fewer
output capacitors and overcomes many hurdles of traditional
digital approach, which uses non-linear, discrete control method
for both voltage loop and current balance loop and runs into beat
frequency oscillation and non-linear response. The ISL6388 …
