ISL62883CEVAL2Z User Guide
Introduction
Interface Connections
The ISL62883CEVAL2Z evaluation board demonstrates
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.

• TP11: Monitor the ISEN2 pin.
Jumper Descriptions
• TP13: Monitor the PGOOD pin.
• TP10: Monitor the ISEN3/FB2 pin.
• TP12: Input side of the compensator.
• 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 ISL62883 is configured for 3-phase or
2-phase application. Tie ISEN2 to 5V when the
ISL62883 is configured for 1-phase application.
• TP14: Monitor the VSEN pin.
• 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 ISL62883 is configured for 3-phase,
2-phase application. Leave ISEN1 floating when
the ISL62883 is configured for 1-phase application
• TP19: Monitor the positive side of C82.
• J3: If installed, the ISEN3/FB2 pin will be
connected to the power stage. If uninstalled, the
ISEN3/FB2 pin will be disconnected from the power
stage. Install J3 when the ISL62883 is configured
for 3-phase application. Uninstall J3 when the
ISL62883 is configured for 2-phase or 1-phase
application.
• TP24: Monitor the VID3 pin.
• J4: Set the PWM3 pin configuration. PWM3 can be
connected to the ISL6208 driver, tied to +5V, GND
or left floating. Connect PWM3 to the ISL6208
driver when the ISL62883 is configured for
3-phase application. Tie PWM3 to 5V when the
ISL62883 is configured for 2-phase or 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/TP30 WHILE J16 IS
INSTALLED! IT’LL SHORT THE +5V AND THE
+3.3V POWER SUPPLIES. When measuring
board efficiency, uninstall J16 and apply +3.3V to
TP/37/TP30.
