Introduction
The ISL62882CEVAL2Z evaluation board demonstrates
the performance of the ISL62882 multiphase
synchronous-buck PWM V CORE controller implementing
Intel IMVP-6.5 protocol. The ISL62882 features Intersil's
Robust Ripple Regulator (R 3 ) technology. An on-board
dynamic-load generator is included for evaluating the
transient-load response. It applies a 300μs pulse of
approximately 25m Ω load across V O and PGND.
