Product details
Overview
ZL8801-2PH-DEMO1Z from Renesas Electronics is a 6-layer demonstration board for the ZL8801 digital dual-phase synchronous buck controller, delivering up to 80A at 1.2V from a 12V input with 500kHz switching frequency and 91% peak efficiency. It integrates ISL99140 DrMOS power stages, PMBus™ interface, and supports voltage sequencing, margining, and thermal monitoring.
For engineers reviewing the ZL8801-2PH-DEMO1Z datasheet, ZL8801-2PH-DEMO1Z pinout, ZL8801-2PH-DEMO1Z application, or ZL8801-2PH-DEMO1Z equivalent, this board enables rapid evaluation of digital power management features including ChargeMode™ control, dynamic load step response (±1% at 10A/µs), and real-time telemetry via PowerNavigator™ software on Windows XP/7/8.
Technical Context
The ZL8801-2PH-DEMO1Z implements a functionally optimized layout for the ZL8801 controller, featuring two parallel ISL99140 DrMOS modules per phase, differential voltage sensing, kelvin current sense traces, and dedicated analog/digital ground separation (SGND/DGND) to preserve signal integrity. It supports full PMBus command set including ON_OFF_CONFIG, VOUT_COMMAND, and IOUT_OC_FAULT_LIMIT.
Board-level functionality includes hardware enable/disable toggle switch, power-good LED indicators, right-angle headers for daisy-chaining multiple boards via DDC bus, and USB-to-PMBus adapter interface (ZLUSBEVAL3Z). Default configuration sets VOUT=1.0V, fSW=500kHz, VOUT_OV_FAULT_LIMIT=1.105V, and IOUT_OC_FAULT_LIMIT=50A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4.5V to 14V - Supports common intermediate bus voltages including 5V, 12V, and 13.2V telecom rails. |
| VOUT Range | 0.54V to 2.0V (configurable to 5.5V with 6.3V output capacitors) - Covers core voltage requirements for modern FPGAs, ASICs, and processors. |
| Max Output Current | 80A continuous - Achieved via dual-phase interleaved operation with ISL99140 DrMOS devices and low-DCR inductors (0.230µH). |
| Switching Frequency | 500kHz - Balances efficiency, component size, and transient response; configurable via FREQUENCY_SWITCH PMBus command. |
| Efficiency | 91% at 40A, VIN=12V, VOUT=1.2V - Reflects combined losses from controller, DrMOS, inductors, and output capacitors under typical load conditions. |
| Dynamic Response | ±1% deviation for 50%→100%→50% load step at di/dt = 10A/µs - Enabled by compensation-free ChargeMode™ control architecture. |
| Output Ripple | ±1% - Measured under steady-state 80A load, indicating effective filtering using 100µF/22µF/4.7µF multilayer ceramic capacitor stack. |
