ISL1904FAZ

Overview

The ISL1904FAZ is a dimmable AC mains LED driver IC featuring primary side regulation and power factor correction. It operates as a critical conduction mode flyback controller for single-stage AC-to-constant-current conversion. Designed for high-power LEDs, it accepts an input voltage range of 9 V to 20 V and utilizes surface mount technology.

Feature Summary

Integrates power factor correction with primary side regulation
Supports dimming functionality for AC mains applications
Optimized for high-power LED loads

Applications

Dimmable AC mains LED lighting systems
High-power LED drivers requiring PFC
Single-stage AC-to-DC constant current converters

Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status via the latest datasheet. Check for active obsolescence notices or product change notifications prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring integrated PFC and dimming in a single-stage topology. Ensure the application supports the specified input voltage range. Verify thermal management requirements for the QSOP package in high-power scenarios.

Part Context

This part belongs to the ISL1903/ISL1904 series of LED lighting drivers from Renesas (formerly Intersil). These components target general illumination markets needing compliant, cost-effective solutions for mains-powered fixtures without secondary side sensing.
