May 5, 2017 Multiphase PWM Regulator for IMVP-6.5 Mobile CPUs and GPUs
The ISL62883C is a multiphase PWM buck regulator for
microprocessor 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 ISL62883C uses two integrated
gate drivers and an external gate driver to provide a complete
solution. The PWM modulator is based on the Intersil Robust
Ripple Regulator (R3в„ў) technology. Compared with traditional
modulators, the R3 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 ISL62883C can be configured as a CPU or graphics Vcore
controller and is fully compliant with Intel IMVP-6.5
specifications. It responds to PSI# and DPRSLPVR signals by
adding or dropping PWM3 and Phase 2 respectively, adjusting …
