Renesas ISL62883CEVAL2Z

Overview

The ISL62883CEVAL2Z from Renesas Electronics is an evaluation board designed to demonstrate the performance of the ISL62883 multiphase synchronous-buck PWM VCORE controller implementing Intel IMVP-6.5 protocol, featuring Robust Ripple Regulator (R3) technology, supporting 1–3-phase configurations, and incorporating an on-board dynamic-load generator for transient-response testing under real-world CPU core voltage regulation conditions.

For engineers reviewing the ISL62883CEVAL2Z datasheet, ISL62883CEVAL2Z test setup, ISL62883CEVAL2Z interface connections, or ISL62883CEVAL2Z application notes, this board provides validated reference design, full schematic documentation, configurable phase selection via jumpers (J1–J4), DIP-switch control (S1, U2), and dedicated test points for PHASE1/2/3, VO, VIN, and critical control signals including VR_ON, PSI#, DPRSLPVR, and VID0–VID6.

Technical Context

The ISL62883CEVAL2Z implements a complete IMVP-6.5-compliant VCORE power delivery solution with support for 1-, 2-, or 3-phase operation, selectable via hardware jumpers (J1–J4) and DIP switches (S1, U2). It integrates the ISL62883HRZ QFN-40 controller, ISL6208CBZ MOSFET driver, HIP2100IBZ half-bridge driver, and rPGA989 CPU socket interface.

It features a programmable 0–1.5V output voltage range, 4.5–20V input voltage capability, 75A full-load current rating, and 300kHz PWM switching frequency. The on-board dynamic-load generator applies a 300µs, ~25mΩ pulse across VO and PGND to evaluate transient response without external equipment.

FAQ

What is the primary function of the ISL62883CEVAL2Z evaluation board?

The ISL62883CEVAL2Z evaluation board is a fully assembled, tested reference platform for the ISL62883HRZ IMVP-6.5 VCORE controller. Its primary function is to enable engineers to validate transient response, efficiency, phase configuration behavior, and VID-programmed voltage regulation in real-world CPU power delivery scenarios-without requiring custom PCB design or layout verification. It includes all necessary power stages, drivers, sensing, and interface circuitry to replicate a production VRM.

Which CPU interface standard does the ISL62883CEVAL2Z support?

The ISL62883CEVAL2Z supports Intel's IMVP-6.5 specification for mobile and desktop CPU core voltage regulation. It implements the full 7-bit VID bus (VID0–VID6), VR_ON, PSI#, DPRSLPVR, PGOOD, and VR_TT# signaling required by IMVP-6.5, and includes an rPGA989 CPU socket (U4) to physically interface with compatible processors during testing.

How is phase count configured on the ISL62883CEVAL2Z?

Phase count (1-, 2-, or 3-phase) on the ISL62883CEVAL2Z is configured using physical jumpers J1–J4 and DIP switches S1 and U2. J1 and J2 set ISEN1/ISEN2 connections, J3 enables/disables ISEN3/FB2 for 3-phase operation, and J4 configures PWM3 output routing. These hardware selections directly determine how the ISL62883HRZ interprets its current-sense inputs and drives gate signals-ensuring correct loop compensation and driver activation per phase count.

Does the ISL62883CEVAL2Z include an on-board dynamic load generator?

Yes, the ISL62883CEVAL2Z includes an integrated dynamic-load generator based on the HIP2100IBZ half-bridge driver and SUD50N03-07 MOSFET (Q15). When enabled via S5 switch, it applies a precise 300µs pulse with ~25mΩ effective resistance across VO and PGND-enabling repeatable, high-slew-rate load-step testing of transient response without external electronic loads or complex triggering setups.

What documentation and design files are provided with the ISL62883CEVAL2Z?

The ISL62883CEVAL2Z is accompanied by AN1557 (User's Manual, Rev 0.00), which includes complete design criteria, interface connection diagrams, DIP-switch and jumper configuration tables, test-point mapping, bill of materials (BOM), full schematic (5 pages), top/bottom silkscreen plots, and 8-layer PCB stack-up drawings. All documentation is publicly available and intended for immediate use in lab validation and design replication.
