Renesas ISL6410AEVAL1

Overview

ISL6410AEVAL1 from Intersil is an evaluation board for the ISL6410A single synchronous buck regulator IC, designed to demonstrate 5.0V ±10% input-to-programmable-output DC-DC conversion (1.2V/1.8V/3.3V) with 600mA continuous output, 750kHz switching frequency, and integrated N-/P-channel MOSFETs. It supports FPGA, ASIC, and WLAN card core power delivery in compact embedded systems.

For engineers reviewing the ISL6410AEVAL1 datasheet, ISL6410AEVAL1 pinout, ISL6410AEVAL1 application, or ISL6410AEVAL1 equivalent, this board enables rapid validation of ISL6410A-based 5V-to-3.3V/1.8V/1.2V point-of-load regulation, synchronization capability (500kHz–1MHz), power-good monitoring, and thermal/overcurrent protection under real load conditions.

Technical Context

The ISL6410AEVAL1 implements the ISL6410A IC in MSOP-10 package with VIN = 5.0V ±10%, VSET-configurable output (1.2V/1.8V/3.3V), and fixed 750kHz oscillator synchronized via SYNC pin. It incorporates external 12µH inductor, 10µF input/output ceramic capacitors, and a 0.01µF CT capacitor for 25ms RESET timeout.

Board-level features include EN-controlled startup with 5.5ms soft-start, open-drain PG signal referenced to 5V logic, UVLO thresholds at 4.1V–4.45V, and thermal shutdown at 150°C with 20–25°C hysteresis - all directly exposing ISL6410A's current-mode PWM control loop, internal slope compensation, and integrated gate drivers.

FAQ

What is the primary function of the ISL6410AEVAL1 evaluation board?

The ISL6410AEVAL1 evaluation board demonstrates the ISL6410A synchronous buck regulator IC, enabling engineers to validate 5.0V input-to-programmable-output (1.2V/1.8V/3.3V) DC-DC conversion with 600mA capability, 750kHz switching, and full protection features. It provides a ready-to-use platform for testing ISL6410A behavior under real load, thermal, and transient conditions before final PCB integration.

Which input voltage range does the ISL6410AEVAL1 support, and how is it aligned with the ISL6410A IC?

The ISL6410AEVAL1 supports 4.5V to 5.5V input, precisely matching the ISL6410A's specified VIN range of 5.0V ±10%. This ensures operation within the IC's guaranteed UVLO thresholds (4.1V–4.45V), quiescent current limits, and thermal performance envelope as defined in the FN9149 datasheet.

How is output voltage configured on the ISL6410AEVAL1, and what options are available?

Output voltage on the ISL6410AEVAL1 is configured via the VSET pin per ISL6410A datasheet Table 1: connecting VSET to GND yields 1.2V, to VIN yields 3.3V, and leaving it open yields 1.8V. These configurations are implemented using onboard jumpers or solder pads, allowing direct verification of all three factory-programmed output options without modifying the ISL6410A IC itself.

Does the ISL6410AEVAL1 support external clock synchronization, and what is the valid frequency range?

Yes, the ISL6410AEVAL1 exposes the SYNC pin of the ISL6410A IC and supports external clock synchronization from 500kHz to 1MHz, as specified in the electrical characteristics table. The board includes appropriate AC-coupling and termination provisions to interface with standard CMOS clock sources while maintaining signal integrity and avoiding false triggering.

What protection and monitoring functions are accessible on the ISL6410AEVAL1 board?

The ISL6410AEVAL1 provides access to all ISL6410A protection and monitoring signals: open-drain PG (power good) referenced to 5V logic, EN (enable) for controlled startup/shutdown, RESET (supervisory output with 25ms timeout), and thermal shutdown indication via junction temperature sensing. These allow full system-level validation of fault response, sequencing, and reliability margins.
