描述

The iW3658 is a highly integrated, high-performance LED driver for easy, low-cost dimmable bulb designs up to 15W. It features an integrated FET for low BOM cost and Renesas' proprietary dimming control to enable compatibility with a wide range of dimmers, including TRIAC and digital. It also provides smooth, flicker-free dimming across a wide dimming range.

Renesas' patented VCC control technology used in the iW3658 removes the need for external start-up circuitry, eliminates ghosting, and provides fast start-up and consistent VCC charging control for stable parallel lamp performance to ensure simultaneous turn-on.

Full protection features in the iW3658 include Renesas' unique over-temperature protection (OTP) derating, which protects the LED driver by reducing output current drive to the LEDs during an over-temperature event.
