描述 Description

Enables Easy, Low-Cost Bulb Design
The iW3659 is a high-performance LED driver for easy, low-cost dimmable bulb designs up to 25W. It features Dialog’s 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.
Dialog’s patented VCC control technology used in the iW3659 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 iW3659 include Dialog's unique over-temperature protection (OTP) derating, which protects the LED driver by reducing output current drive to the LEDs during an over-temperature event. More on OTP here.
For designs requiring an internal FET, see iW3658.
