Product details
Overview
ISL68301EVAL1Z from Renesas Electronics is a fully assembled, 6-layer FR4 evaluation board for the ISL68301 single-phase digital DC/DC controller. It supports default operation at 1.0V output, 500kHz switching frequency, and 7–16V input, delivering up to 30A load current with >88% peak efficiency. The board enables full characterization of ChargeMode™ control, PMBus programmability, and dynamic load response in server, telecom, and FPGA power applications.
For engineers reviewing the ISL68301EVAL1Z datasheet, ISL68301EVAL1Z pinout, ISL68301EVAL1Z application, or ISL68301EVAL1Z equivalent, this page delivers verified board-level specifications, configuration options (Pin-Strap and PMBus), PowerNavigator™ integration details, and hardware interface guidance for rapid digital power validation.
Technical Context
The ISL68301EVAL1Z implements Renesas' ChargeMode™ control architecture - a compensation-free, single-cycle transient response modulation scheme that eliminates loop tuning while reducing output capacitance requirements. It interfaces directly with the ISL68301IRAZ controller and ISL99227BFRZ-T DrMOS power stage to form a complete digital point-of-load solution.
Board-level functionality includes on-board dynamic load stepping, dual configuration paths (hardware pin-strapping via 0402 resistors and software-based PMBus via ZLUSBEVAL3Z adapter), and Digital-DC™ bus daisy-chaining support for multi-rail sequencing. All critical parameters - VOUT, fSW, fault thresholds, soft-start, and current limit - are configurable either at power-up or runtime.

FAQ
What is the primary function of the ISL68301EVAL1Z evaluation board?
The ISL68301EVAL1Z evaluation board is a complete hardware platform for evaluating the ISL68301 digital DC/DC controller. It enables engineers to validate ChargeMode™ control performance, configure VOUT, fSW, fault limits, and sequencing via Pin-Strap resistors or PMBus commands using PowerNavigator™, and test dynamic load response up to 35A. The board includes the ISL68301IRAZ controller, ISL99227BFRZ-T DrMOS stage, and ZLUSBEVAL3Z interface adapter - all pre-assembled and tested.
Does the ISL68301EVAL1Z require external software to operate?
Yes - the ISL68301EVAL1Z requires Renesas PowerNavigator™ software for full PMBus-based configuration and real-time monitoring. PowerNavigator runs on Windows PCs and communicates with the board via the included ZLUSBEVAL3Z USB-to-PMBus adapter. However, basic operation (e.g., fixed 1.0V/500kHz output) is possible without software using default pin-straps - no PC or software needed for initial power-up testing.
Can the ISL68301EVAL1Z be used for multi-phase or multi-rail evaluation?
No - the ISL68301EVAL1Z is a single-phase evaluation board for the ISL68301 controller only. However, it supports Digital-DC™ (DDC) bus daisy-chaining, enabling synchronization and coordinated sequencing with other Renesas digital power evaluation boards (e.g., ISL68201, ISL68203). This allows system-level validation of multi-rail power trees without modifying the ISL68301EVAL1Z hardware itself.
What input voltage range does the ISL68301EVAL1Z support by default, and how is it extended?
By default, the ISL68301EVAL1Z operates from VIN = 7V to 16V. To extend support down to 4.5V, resistors R4 and R6 must be populated to tie V5 and VG directly to VIN - as specified in Section 2.1 of UG169. This modification enables compatibility with lower-voltage intermediate bus architectures while maintaining full controller functionality and PMBus communication integrity.
How is output voltage adjusted on the ISL68301EVAL1Z?
Output voltage on the ISL68301EVAL1Z is adjustable in two ways: (1) via Pin-Strap mode using 1% 0402 resistors at R3 and R5 (per ISL68301 datasheet tables), enabling fixed VOUT from 0.5V to 2.5V without software; or (2) dynamically via PMBus command VOUT_COMMAND using PowerNavigator™. Default factory setting is VOUT = 1.0V (0x2000 hex), with VOUT_MAX = 1.15V and margining limits preconfigured in the sample configuration file.
