ISL6219A
Microprocessor CORE Voltage Regulator
Precision Multi-Phase BUCK PWM
Controller for Mobile Applications
The ISL6219A provides core-voltage regulation by driving up
to three interleaved synchronous-rectified buck-converter
channels in parallel. Intersil multi-phase controllers together
with ISL6207 gate drivers form the basis for the most reliable
power-supply solutions available to power the latest
industry-leading microprocessors. Multi-phase buck-
converter architecture uses interleaved timing to multiply
ripple frequency and reduce input and output ripple currents.
Lower ripple results in lower total component cost, reduced
dissipation, and smaller implementation area. Pre-
configured for 3-phase operation, the ISL6219A offers the
flexibility of 2-phase operation. Simply connect the unused
PWM pin to +5V. The channel switching frequency is
adjustable in the range of 100kHz to 1.5MHz giving the
designer the ultimate flexibility in managing the balance
between high-speed response and good thermal
management.
New features on the ISL6219A include Dynamic-VID
technology allowing seamless on-the-fly VID changes with
no need for any additional external components. When the
ISL6219A receives a new VID code, it incrementally steps
the output voltage to the new level. Dynamic VID changes
are fast and reliable with no output voltage overshoot or
undershoot.
Like other Intersil multiphase controllers, the ISL6219A uses
cost and space-saving r
DS(ON)
sensing for channel current
balance and dynamic voltage positioning. Channel current
balancing is automatic and accurate with the integrated
current-balance control system. Over current protection can
be tailored to any application with no need of additional
parts.
An integrated DAC decodes the 5-bit logic signal present at
VID0-VID4 and provides an accurate reference for precision
voltage regulation. The high-bandwidth error amplifier and
accurate voltage reference all work together to provide
better than 0.8% total system accuracy, and to enable the
fastest transient response available. A window comparator
toggles PGOOD if the output voltage moves out of range
and acts to protect the load in case of over voltage.
