Product details
Overview
The ISL81601EVAL2Z from Renesas Electronics is a fully assembled, tested evaluation board for the ISL81601 60V high-voltage synchronous buck-boost controller. It supports bi-directional operation, delivers up to 5A at 48V output, and features programmable PWM/DEM mode, CC/HICCUP OCP, soft-start, and comprehensive protection (UV/OV/OC/OT). Designed for industrial power conversion validation in telecom, server, and battery backup systems.
For engineers reviewing the ISL81601EVAL2Z datasheet, ISL81601EVAL2Z pinout, ISL81601EVAL2Z application, or ISL81601EVAL2Z equivalent, this board enables rapid characterization of the ISL81601's 32–60V input range, 200kHz switching frequency, 48V/5A output capability, bi-directional control, and real-time OCP/OTP/PGOOD monitoring under load and transient conditions.
Technical Context
The ISL81601EVAL2Z implements the ISL81601 controller in a 38-pin TSSOP package driving four external N-channel MOSFETs (Infineon BSC123N08NS3GATMA1) and a 22µH Vishay IHLP6767GZER220M11 inductor. It operates across -40°C to +85°C ambient with no forced airflow required at 5A continuous load.
Board-level configuration is managed via three 3-pin headers (J7, J8, J9): J8 selects PWM or discontinuous conduction mode (DEM); J9 sets constant-current or hiccup overcurrent protection; J7 enables/disables VIN limiting. Test points TP1–TP28 provide direct access to all critical IC pins and signal nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 32V to 60V - supports wide-range industrial DC inputs including 48V telecom and battery systems. |
| Output Voltage | 48V fixed - configured for standard telecom/datacom rail; adjustable via feedback resistor network (R2/R3). |
| Max Output Current | 5A continuous - validated at room temperature without airflow; limited by FETs and inductor thermal performance. |
| Switching Frequency | 200kHz - factory-set operating point balancing efficiency, EMI, and component size for high-power density design. |
| OCP Threshold | ≥5.5A at ambient - provides margin above rated 5A load while enabling reliable short-circuit response. |

FAQ
What is the primary function of the ISL81601EVAL2Z?
The ISL81601EVAL2Z is an evaluation board built around the ISL81601 60V synchronous four-switch buck-boost controller. Its purpose is to enable engineers to validate the controller's performance-including bi-directional operation, 32–60V input handling, 48V/5A output regulation, PWM/DEM mode selection, and UV/OV/OC/OT protection-under real-world load, line, and transient conditions before integrating into final designs.
Does the ISL81601EVAL2Z support bi-directional power flow?
Yes, the ISL81601EVAL2Z supports bi-directional operation as documented in Section 2.3 of its User's Manual (UG160 Rev.0.00). To enable it, the FBI pin must be floated and PWM mode selected via jumper J8; the supercapacitor voltage must exceed 48V, and input voltage must be set >36V before charging. This functionality is intrinsic to the ISL81601 controller and verified on the ISL81601EVAL2Z board.
What are the key configurable features accessible on the ISL81601EVAL2Z?
The ISL81601EVAL2Z offers three hardware-configurable features via jumpers: J8 selects forced PWM or discontinuous conduction mode (DEM); J9 chooses constant-current limit or hiccup-mode overcurrent protection; J7 enables or disables VIN limiting. These settings allow immediate evaluation of different control strategies and protection behaviors without firmware or solder changes on the ISL81601EVAL2Z.
What external components define the ISL81601EVAL2Z's 5A current rating?
The 5A continuous output rating of the ISL81601EVAL2Z is determined by its selected power stage: four Infineon BSC123N08NS3GATMA1 80V/55A MOSFETs, a Vishay IHLP6767GZER220M11 22µH/12A inductor, and multiple high-reliability TDK/Murata output capacitors. Thermal performance at 5A was validated without airflow at room temperature, per UG160 page 4.
Can the ISL81601EVAL2Z be used to evaluate soft-start and pre-bias start-up behavior?
Yes, the ISL81601EVAL2Z supports both programmable soft-start (via SS/TRK pin and external capacitor) and pre-bias output start-up, as stated in Section 1.1 Key Features of UG160. The board includes dedicated test points (e.g., TP12 for SS/TRK) and jumper-accessible EN/UVLO control, allowing direct measurement and tuning of ramp time and startup sequencing for the ISL81601 controller on the ISL81601EVAL2Z.
