ISL62883CEVAL2Z User Guide
Introduction
The ISL62883CEVAL2Z evaluation board demonstrates
the performance of the ISL62883 multiphase
synchronous-buck PWM V CORE controller implementing
Intel IMVP-6.5 protocol. The ISL62883 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.
