Multiphase PWM Regulator for IMVP-6.5™ Mobile CPUs Evaluation Board


The ISL62883CEVAL2Z and ISL62883EVAL2Z evaluation boards demonstrate the performance of the ISL62883 multiphase synchronous-buck PWM VCORE controller implementing Intel IMVP-6.5 protocol. The ISL62883 features Intersil's Robust Ripple Regulator (R3) technology. An on-board dynamic-load generator is included for evaluating the transient-load response. It applies a 300µs pulse of approximately 25mΩ load across VO and PGND.
