Product details
Overview
ISL68201-99135DEMO1Z from Intersil (now Renesas) is a 6-layer demonstration board implementing a compact 13mm×13mm, 20A single-phase synchronous buck converter using the ISL68201 PWM controller and ISL99135B DrMOS power stage. It supports 4.75V–14.5V input, 1V output at full load, 500kHz switching frequency, PMBus/SMBus/I²C digital control, and on-board transient load testing.
For engineers reviewing the ISL68201-99135DEMO1Z datasheet, ISL68201-99135DEMO1Z pinout, ISL68201-99135DEMO1Z application, or ISL68201-99135DEMO1Z equivalent, this page delivers verified board-level specifications, PowerNavigator™ software integration details, transient response validation data, thermal performance metrics at 20A, and hardware configuration guidance for digital power system evaluation.
Technical Context
The ISL68201-99135DEMO1Z implements Intersil's R4™ modulator architecture with fast transient response, internal compensation, and DCR-based current sensing using the ISL99135B DrMOS. It integrates programmable boot voltage, selectable switching frequency (400/500/600kHz), FCCM light-load mode, and comprehensive fault protection including overvoltage, overcurrent (retry/latch), short-circuit, and overtemperature.
Board-level features include cascading PMBus connectors (JP2/J9/J10), on-board transient load with adjustable di/dt via function generator interface (FG_DRIVE2/FG_GND2), resistor-programmable configuration (PROG1–PROG4), integrated LDOs for single-rail biasing, and remote sensing (VSEN/RGND) routed with strict noise isolation per layout guidelines.
Key Specifications

FAQ
What is the primary purpose of the ISL68201-99135DEMO1Z?
The ISL68201-99135DEMO1Z is a fully assembled demonstration board used to evaluate the ISL68201 digital PWM controller and ISL99135B DrMOS power stage in a 20A, 13mm×13mm synchronous buck configuration. It enables engineers to validate transient performance, PMBus programming, fault protections, power sequencing, and thermal behavior without designing a custom PCB. The ISL68201-99135DEMO1Z includes all necessary components, test points, and interfaces for rapid lab verification.
Does the ISL68201-99135DEMO1Z require external software to operate?
No - the ISL68201-99135DEMO1Z operates standalone using hardware configuration via PROG1–PROG4 resistors and the ENABLE switch. However, Intersil's PowerNavigator™ software (Windows-only) is required to access full PMBus functionality - including real-time telemetry, margining, VOUT ramp control, and fault log retrieval. The ISL68201-99135DEMO1Z includes ZLUSBEVAL3Z PMBus dongle and USB cable for PC connectivity.
What input and output voltage ranges does the ISL68201-99135DEMO1Z support?
The ISL68201-99135DEMO1Z is configured for 4.75V–14.5V input and delivers 1V at up to 20A. Its underlying ISL68201 controller supports 4.5V–24V input and 0.5V–5.5V output, but the demo board's passive components (capacitors, inductor, thermal design) are optimized for the 1V/20A/12VIN use case. Modifications to support other outputs (e.g., 3.3V, 5V) require L/DCR retuning and capacitor rating adjustments per Table 1 in UG088.
How is transient response tested on the ISL68201-99135DEMO1Z?
The ISL68201-99135DEMO1Z includes an on-board transient load circuit (RLT1//RLT2 = 50mΩ) driven by an external function generator via FG_DRIVE2/FG_GND2 connectors. Load step amplitude and di/dt are controlled by the generator; typical tests use 0.25A→12.75A steps at 25A/µs. Transient waveforms (VOUT, PHASE, LOAD) are captured at TP15 and standard test points, with results documented in Figures 23–26 of UG088.
Can multiple ISL68201-99135DEMO1Z boards be connected on the same PMBus?
Yes - the ISL68201-99135DEMO1Z includes cascading PMBus connectors (JP2, J9, J10) and supports multi-board communication. Each board must be assigned a unique SMBus address (default 0x60) via PROG2 resistor configuration to avoid bus conflicts. Pull-up impedance must be adjusted based on total bus capacitance, and SCL/SDA routing must follow SMBus layout rules (20-mil spacing, >30-mil separation from noisy traces) as specified in Table 2 of UG088.
