Multiphase PWM Regulator for IMVP-6.5? Mobile CPUs
and GPUs
ISL62882, ISL62882B
The ISL62882 is a multiphase PWM buck regulator for
miroprocessor or graphics processor core power supply. The
multiphase buck converter uses interleaved phases to reduce the
total output voltage ripple with each phase carrying a portion of the
total load current, providing better system performance, superior
thermal management, lower component cost, reduced power
dissipation, and smaller implementation area. The ISL62882 uses
two integrated gate drivers to provide a complete solution. The PWM
modulator is based on Intersil's Robust Ripple Regulator (R 3 )
technology?. Compared with traditional modulators, the R 3 ?
modulator commands variable switching frequency during load
transients, achieving faster transient response. With the same
modulator, the switching frequency is reduced at light load,
increasing the regulator efficiency.
The ISL62882 can be configured as CPU or graphics Vcore controller
and is fully compliant with IMVP-6.5? specifications. It responds to
PSI# and DPRSLPVR signals by adding or dropping Phase 2,
adjusting overcurrent protection threshold accordingly, and
entering/exiting diode emulation mode. It reports the regulator
output current through the IMON pin. It senses the current by using
either discrete resistor or inductor DCR whose variation over
temperature can be thermally compensated by a single NTC
thermistor. It uses differential remote voltage sensing to accurately
regulate the processor die voltage. The unique split LGATE function
further increases light load efficiency. The adaptive body diode
conduction time reduction function minimizes the body diode
conduction loss in diode emulation mode. User-selectable overshoot
reduction function offers an option to aggressively reduce the output
capacitors as well as the option to disable it for users concerned
about increased system thermal stress. The ISL62882 offers the
FB2 function to optimize 1-phase performance.
The ISL62882B has the same functions as the ISL62882, but
comes in a different package.
