Renesas ISL8130EVAL2Z

Overview

The ISL8130EVAL2Z from Renesas Electronics is an evaluation board designed to demonstrate and validate the ISL8130 synchronous buck controller in voltage-mode operation, supporting up to 25A output current at 5V with 280kHz switching frequency and 94% peak efficiency at 12V input.

For engineers reviewing the ISL8130EVAL2Z datasheet, ISL8130EVAL2Z test setup, ISL8130EVAL2Z quick evaluation procedure, or ISL8130EVAL2Z component selection guidance, this board enables rapid validation of transient response, load regulation, overcurrent protection, soft-start behavior, and ripple performance under real-world power delivery conditions.

Technical Context

The ISL8130EVAL2Z implements a complete 5V/25A synchronous buck converter using dual N-channel MOSFETs (BSC057N03LS), a 0.9µH SER2010-901ML inductor, and multi-capacitor output filtering including 180µF OSCON and 470µF aluminum electrolytic capacitors for low-impedance bulk storage.

It supports flexible reference configuration via the REFIN pin-selecting either the internal 0.6V reference or an external 0.6–1.25V source-and includes hardware jumpers (J1, J8) for internal reference selection and enable/disable control, with dedicated test points for VIN, VOUT, PHASE, and PGOOD monitoring.

FAQ

What is the primary function of the ISL8130EVAL2Z?

The ISL8130EVAL2Z is a fully assembled evaluation board that demonstrates the ISL8130 synchronous buck controller in a working 5V/25A power stage. It provides a reference design for voltage-mode control, including all necessary passive components, MOSFETs, and layout techniques to validate performance metrics such as efficiency, load regulation, and transient response before custom design implementation.

Which controller IC does the ISL8130EVAL2Z evaluate?

The ISL8130EVAL2Z evaluates the ISL8130IAZ-a wide-input (5.6V–16V), voltage-mode synchronous buck controller in a 20-lead QSOP package. The board implements the ISL8130's full feature set, including internal 0.6V reference selection, external reference support, overcurrent protection, soft-start, and PGOOD signaling-all accessible via onboard jumpers and test points.

What input and output configurations are validated on the ISL8130EVAL2Z?

The ISL8130EVAL2Z is validated for 12V input and 5V/25A output operation, with electrical specifications confirming 4.75–5.25V output regulation, ≤280kHz switching frequency, and ≥94% peak efficiency. Input range testing covers 5.6–16V, and load step testing verifies stability up to 25A with controlled transient response per Figure 9 in AN1909.

How do I configure the ISL8130EVAL2Z for internal vs. external reference operation?

Configure the ISL8130EVAL2Z for internal reference by setting jumper J1 to the "Internal Reference" position (shorting pins 1–2), which connects REFIN to VCC5 and selects the 0.6V internal reference. For external reference, disconnect J1 and apply a 0.6–1.25V source directly to the REFIN test point (P8), as specified in the AN1909 user manual section "External Reference."

What test equipment is required to evaluate the ISL8130EVAL2Z?

Evaluating the ISL8130EVAL2Z requires a 0–30V/30A DC power supply, an electronic load capable of sinking 25A, a 100MHz quad-trace oscilloscope with proper probe setup (per Figure 3), and digital multimeters for DC voltage and current measurement. Test points VOUT, VIN, PHASE, and PGOOD are provided for non-invasive monitoring without high-current routing through probes.
