Product details
Overview
ISL8272MEVAL2Z from Intersil (now Renesas) is an evaluation board designed to validate the current-sharing operation of three ISL8272M 50A digital DC/DC power modules in parallel, delivering up to 150A continuous output at 1.2V with 421kHz switching frequency and <5mVP-P output ripple. It supports both pin-strap configuration and full PMBus™ programmability via ZLUSBEVAL3Z USB adapter and PowerNavigator™ software.
For engineers reviewing the ISL8272MEVAL2Z datasheet, ISL8272MEVAL2Z pinout, ISL8272MEVAL2Z application, or ISL8272MEVAL2Z equivalent, this board enables rapid validation of high-current digital power system features including ASCR gain/residual tuning, VOUT droop-based current sharing, transient load response, control loop Bode analysis, and multi-board daisy-chained PMBus communication.
Technical Context
The ISL8272MEVAL2Z implements a 3-module parallel architecture using ISL8272MAIRZ modules, each featuring ChargeMode™ control (ASCR), dual-phase synchronous buck topology, integrated inductors, and PMBus-compliant digital interface. Default configuration delivers 150A at 1.2V with 0.1mV/A VOUT droop for passive current sharing.
It provides dedicated test circuitry for transient load evaluation (using two parallel BSC010NE2LS MOSFETs), voltage loop Bode plot measurement (via R58 injection point), and remote sensing with thermal-aware layout on a 6-layer FR4 board (5.8" × 6.1", 2-oz copper). Pin-strap resistors configure VOUT, soft-start, UVLO, ASCR parameters, and PMBus address without software.

FAQ
What is the primary function of the ISL8272MEVAL2Z evaluation board?
The ISL8272MEVAL2Z evaluation board is specifically designed to demonstrate and validate the current-sharing behavior of three ISL8272M 50A digital DC/DC modules operating in parallel. It enables engineers to verify 150A output capability, tune ASCR control parameters, configure VOUT droop, perform transient load testing using onboard MOSFETs, and conduct voltage-loop Bode analysis-all using either pin-strap resistors or PMBus commands via PowerNavigator™ software.
Does the ISL8272MEVAL2Z include hardware for transient load testing?
Yes, the ISL8272MEVAL2Z includes dedicated transient load test circuitry: two parallel BSC010NE2LS N-channel MOSFETs (100A each) placed adjacent to the remote voltage sense location, with dual 10mΩ current-sense resistors for monitoring. The gate driver pulse is injected via J16 ("TRANSIENT LOAD INPUT"), and load current is monitored at J15 ("TRANSIENT LOAD MONITOR"), supporting controlled step-load evaluation without external equipment.
Can the ISL8272MEVAL2Z be used with multiple evaluation boards in a daisy-chain configuration?
Yes, the ISL8272MEVAL2Z supports daisy-chained PMBus communication via its "PMBus DONGLE IN" and "TO DAISY CHAIN PMBus CONNECTION" headers. When used with the ZLUSBEVAL3Z USB-to-PMBus adapter, multiple ISL8272MEVAL2Z boards-or other Renesas digital power evaluation boards-can share a single USB connection, enabling synchronized configuration, monitoring, and fault logging across complex multi-rail systems.
What are the default pin-strap settings for the ISL8272MEVAL2Z?
By default, the ISL8272MEVAL2Z operates in pin-strap mode at VOUT = 1.2V, fSW = 421kHz, soft-start delay = 5ms, soft-start ramp time = 4ms, input UVLO = 4.5V, ASCR gain = 200, ASCR residual = 90, PMBus address = 2Ah/2Bh/2Ch, and 0.1mV/A VOUT droop for three-module current sharing. These values are set by factory-populated 0603 resistors at designated placeholders on the bottom layer.
Is the ISL8272MEVAL2Z compatible with PowerNavigator™ software?
Yes, the ISL8272MEVAL2Z is fully compatible with Renesas PowerNavigator™ evaluation software. When connected via the included ZLUSBEVAL3Z USB-to-PMBus adapter, PowerNavigator™ enables real-time monitoring of VIN, VOUT, IOUT, temperature, duty cycle, and faults; full PMBus command access; configuration file loading; and non-volatile storage of user settings (STORE_USER_ALL) or restoration of factory defaults (RESTORE_FACTORY).
