ISL62883CEVAL2Z, ISL62883EVAL2Z

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

Description

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.

Key Features

  • Precision Multiphase Core Voltage Regulation
  • Microprocessor Voltage Identification Input
  • Supports Multiple Current Sensing Methods
  • Supports PSI# and DPRSLPVR modes
  • Superior Noise Immunity and Transient Response
  • Current Monitor and Thermal Monitor
  • Differential Remote Voltage Sensing
  • High Efficiency Across Entire Load Range
  • Programmable 1-, 2- or 3-Phase Operation
