Product details
Overview
ZL8801-4PH-DEMO1Z from Renesas Electronics is a 4-phase synchronous buck converter demonstration board based on dual ZL8801 digital DC/DC controllers, delivering up to 160A output current at 1.0V nominal with ChargeMode™ control, PMBus™ interface, and preconfigured operation at 515kHz switching frequency for high-efficiency power delivery in server and telecom applications.
For engineers reviewing the ZL8801-4PH-DEMO1Z datasheet, ZL8801-4PH-DEMO1Z pinout, ZL8801-4PH-DEMO1Z application, or ZL8801-4PH-DEMO1Z equivalent, this evaluation board enables rapid validation of multidevice current sharing, voltage margining, sequencing, fault spreading, and real-time VOUT adjustment - all via USB-connected PowerNavigator™ GUI without hardware modification.
Technical Context
The ZL8801-4PH-DEMO1Z implements two ZL8801 controllers (I²C addresses 0x20 and 0x21) operating in interleaved 4-phase configuration with Kelvin-sensed VOUT and IOUT, thermal vias tied to a shared SGND plane, and dual FDMF5821DC DrMOS modules per phase. It supports full PMBus v1.2 command set including VOUT_COMMAND, IOUT_OC_FAULT_LIMIT, and DDC bus daisy-chaining.
Preconfigured parameters include 5ms soft-start delay, 1.0V default VOUT with ±5% margining, 62A per-phase overcurrent protection, and shutdown fault response. Voltage tracking is explicitly disabled per design - confirming absence of track-configurable operation on this board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 6.5V to 14V input - supports standard 12V server rails with 6.0V UV fault cutoff and 14.4V OV shutdown. |
| VOUT Range | 0.6V to 3.6V programmable output - covers DDR memory, ASIC core, and FPGA I/O supply requirements. |
| IOUT Rating | 160A continuous output - achieved via four parallel phases (40A/phase), validated with airflow cooling. |
| fSW Range | 300kHz to 1000kHz adjustable switching frequency - factory-set to 515kHz for optimal efficiency/density tradeoff. |
| Interface | I²C/SMBus, PMBus™ v1.2 compliant - enables full telemetry (VOUT, IOUT, temperature), configuration, and fault logging via USB dongle. |
| Protection | VOUT OV/UV, IOUT OC/UC, VIN OV/UV, OT (125°C), UT (−45°C) - all configurable via PMBus with shutdown or retry response. |
| Board Layers | 6-layer PCB - optimized for low-inductance power paths, Kelvin sensing, and thermal management using inner-plane SGND duplication. |

FAQ
What is the primary function of the ZL8801-4PH-DEMO1Z?
The ZL8801-4PH-DEMO1Z is a fully assembled 4-phase synchronous buck converter evaluation board built around two ZL8801 digital controllers. It demonstrates multidevice current sharing, PMBus-based configuration, and advanced features like sequencing and fault spreading - enabling rapid validation of high-current power delivery architectures before custom design.
Does the ZL8801-4PH-DEMO1Z support voltage tracking?
No, voltage tracking is not supported on the ZL8801-4PH-DEMO1Z. This is explicitly stated in the user manual: "Voltage Tracking is not supported on the ZL8801-4PH-DEMO1Z." The board's default configuration files (ZL8801_0x20.txt and ZL8801_0x21.txt) confirm TRACK_CONFIG = 0x00 for both controllers.
What software is required to configure the ZL8801-4PH-DEMO1Z?
The PowerNavigator™ GUI from Renesas is required to configure and monitor the ZL8801-4PH-DEMO1Z. It connects via a USB-to-PMBus adapter (included in the kit) and supports full PMBus v1.2 command access - including real-time VOUT adjustment, margining, fault threshold setting, and telemetry readback for the ZL8801-4PH-DEMO1Z.
What is the default output voltage and maximum current rating of the ZL8801-4PH-DEMO1Z?
The ZL8801-4PH-DEMO1Z ships preconfigured for 1.0V output with ±5% margining and delivers up to 160A continuous output current. This is achieved across four interleaved phases (40A per phase), validated under forced-air cooling conditions as specified in AN1948 Rev 0.00.
Can multiple ZL8801-4PH-DEMO1Z boards be synchronized or daisy-chained?
Yes, the ZL8801-4PH-DEMO1Z supports daisy-chaining via its DDC (Digital-DC™) bus connectors (J5 and J8). When connected to other compatible Intersil/Renesas digital power evaluation boards, it enables coordinated sequencing, fault spreading, and master-slave synchronization - extending system-level validation beyond single-board operation.
