1 ISL62882CEVAL2Z User Guide 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 3µs pulse of approximately 25mΩ load across V O and PGND.

2 DIP-Switch Descriptions S1: Set the control signals - S1.1: Set the DPRSLPVR signal - S1.2: Set the PSI# signal U2: Set the VID Jumper Descriptions J1: Set the ISEN2 pin configuration. ISEN2 can be connected to the power stage, tied to +5V, GND or left floating. Connect ISEN2 to the power stage when the ISL62882 is configured for 3- or 2-phase application. Tie ISEN2 to 5V when the ISL62882 is configured for 1-phase application. J2: Set the ISEN1 pin configuration. ISEN1 can be connected to the power stage, tied to +5V, GND or left floating. Connect ISEN1 to the power stage when the ISL62882 is configured for 3-, 2-phase application. Leave ISEN1 floating when the ISL62882 is configured for 1-phase application J16: If installed, the +5V rail supplies the +3.3V rail to the auxiliary circuit on the board. DO NOT APPLY +3.3V TO TP37/TP3 WHILE J16 IS STALLED! IT LL SHORT THE +5V AND THE +3.3V POWER SUPPLIES. When measuring board efficiency, uninstall J16 and apply +3.3V to TP/37/TP3.
