ISL62882EVAL2Z User Guide ® Application Note July 13, 2009 AN1461.1 Author: Jia Wei Introduction Interface Connections The ISL62882EVAL2Z evaluation board demonstrates the performance of the ISL62882 multiphase synchronous-buck PWM VCORE controller implementing Intel IMVP-6.5 protocol. The ISL62882 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. • VIN: Input Voltage to the Power Stage - J5: VIN Positive Power Input - TP31: VIN Positive Voltage Sense - J6: VIN Return Power Input - TP32: VIN Return Voltage Sense Contents of this document include: • VO: Regulated Output Voltage - J11 and J12: VO Positive Power Output - J13 and J14: VO Return Power Output • +5V: +5V Input Voltage - TP29: +5V Positive Input - TP30: +5V Return Input • Design Criteria • Recommended Test Equipment • +12V: Input Voltage for the Dynamic-load Generator - TP3: 12V Positive Input - TP2: 12V Return Input • Interface Connections • Switch Descriptions • DIP Switch Descriptions • Test Point Descriptions J2 • Evaluation Board Documentation - Bill of materials - Schematic - Silk-screen plots - Board layer plots _ ON S3 OFF J1 1 J6 D1 PGND DPRSLPVR PSI# Test Set-up • Jumper Descriptions 0 S1 VID0 VID1 VID2 VID3 VID4 VID5 VID6 VIN + J5 VIN J16 TP37 +3.3V TP29 TABLE 1.
