Product details
Overview
The ISL8107EVAL2Z from Renesas Electronics is an evaluation board for the ISL8107 single-phase PWM controller, configured as a non-synchronous buck converter delivering 12V at up to 5A output with 200kHz switching frequency, 30mV output ripple, and input voltage range of 18–75V. It supports quick-start evaluation via toggle switch SW1 and provides test points TP3/TP4 for output voltage measurement.
For engineers reviewing the ISL8107EVAL2Z datasheet, ISL8107EVAL2Z pinout, ISL8107EVAL2Z application, or ISL8107EVAL2Z equivalent, this board enables rapid validation of high-voltage DC-DC conversion designs using external N-channel MOSFETs, feed-forward compensation, and overcurrent protection - critical for industrial power supplies and telecom rectifiers.
Technical Context
The ISL8107EVAL2Z implements a fixed-frequency voltage-mode PWM control architecture with input voltage feed-forward compensation, enabling stable regulation across wide VIN ranges (18–75V). Its soft-start circuitry uses dual-current ramping (2µA → 33µA) on the ENSS pin to control startup sequencing and prevent inrush current.
It integrates a dedicated high-side gate driver (UGATE output), phase node sensing (PHASE), and PGOOD status signaling. The board's layout includes discrete components for feedback (R1/R2/R4), timing (RT/CT network), and bias supply routing (J1 shunt options for single/dual supply operation).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 12V nominal - precisely regulated output set by FB resistor divider (R1=11.3kΩ, R2=20kΩ, R4=1.24kΩ). |
| Max Load Current | 5A continuous - validated with HC9-220-R 22µH inductor and HAT2175H MOSFET under thermal constraints. |
| Switching Frequency | 200kHz - determined by RT/CT network (C1=8.2nF, R1=11.3kΩ) and internal oscillator. |
| Input Voltage Range | 18V to 75V - supports wide-range industrial and telecom DC inputs; bias supply configurable via J1. |
| Output Ripple | 30mV peak-to-peak - achieved with 100µF/100V aluminum + 150µF OSCON bulk capacitors and ceramic filtering. |
| Start-up Control | ENSS pin with 2µA/33µA dual-rate soft-start - ensures controlled VOUT ramp and prevents overshoot during power-up. |

FAQ
What is the primary function of the ISL8107EVAL2Z?
The ISL8107EVAL2Z is a fully assembled evaluation board for the ISL8107 single-phase PWM controller IC. It implements a non-synchronous buck topology delivering 12V/5A from 18–75V input, enabling engineers to validate loop stability, efficiency, transient response, and protection features without designing from scratch. The ISL8107EVAL2Z includes all necessary passives, MOSFETs, diodes, and test points per AN1459.
How do I configure the ISL8107EVAL2Z for single-supply operation?
To configure the ISL8107EVAL2Z for single-supply operation, install a shunt between pins 2 and 3 of jumper J1. This connects the ISL8107's VBIAS pin to VIN, allowing the controller to derive its bias supply directly from the main input rail. Ensure VIN remains within the ISL8107's 9–75V operating range when using this configuration. The ISL8107EVAL2Z schematic and AN1459 confirm this setup on page 1.
Which IC does the ISL8107EVAL2Z evaluate, and what package is used?
The ISL8107EVAL2Z evaluates the ISL8107IRZ - a 16-lead QFN packaged single-phase PWM controller. U1 on the board is explicitly labeled ISL8107IRZ in the Bill of Materials (AN1459, page 5), and the footprint matches the 16 Ld QFN outline. The ISL8107EVAL2Z provides direct access to all ISL8107 pins including ENSS, COMP, PHASE, BOOT, and PGOOD for probing and modification.
Can the ISL8107EVAL2Z be used to evaluate synchronous rectification?
No - the ISL8107EVAL2Z implements a non-synchronous buck topology using the HAT2175H high-side N-MOSFET and V10P10 Schottky diode (D1) for low-side conduction. The ISL8107 controller itself lacks a complementary low-side gate drive output required for synchronous rectification. The ISL8107EVAL2Z schematic and AN1459 description explicitly state it is a "non-synchronous buck converter topology."
Where are the key test points located on the ISL8107EVAL2Z?
The ISL8107EVAL2Z provides dedicated test points: TP3 and TP4 connect directly to VOUT and PGND for accurate output voltage measurement with a DMM; TP1 and TP2 monitor ENSS and PHASE waveforms respectively; and P5/P6 (VIN/PGND) and P7/P8 (VOUT/PGND) serve as power and load terminals. These locations are annotated in Figures 1 and 2 of AN1459 and confirmed in the schematic on page 4.
