iW3658

Single-Stage SSL LED Driver with Integrated High

Voltage MOSFET for Dimmable Retroﬁt Lamps up to 15W

1 Description

The iW3658 is a highly integrated, high-performance oﬀ-line power supply controller for phase-cut dimmable LED

luminaires. It uses patented PrimAccurate™ primary-side sensing technology to regulate output current accurately

without the need for a feedback circuit. The iW3658 operates at boundary conduction mode to achieve high eﬃciency

and low EMI.

With advanced dimming control technology, the iW3658 can operate with most wall dimmers including leading-edge

dimmers (R-type or R-L type) and trailing-edge dimmers (R-C type). The iW3658 operates in buck-boost mode to

regulate current to the output LEDs.

Dialog’s innovative technology maximizes the iW3658 performance with an integrated high-voltage MOSFET in an SO-7

package, which provides an extra pin spacing between the high voltage MOSFET’s drain and low voltage pins. With

Dialog’s proprietary V_CCregulation circuit, the iW3658’s V_CClevel is well maintained regardless of the LED voltage and

dimmer phase angle, which eliminates the possibility of low end ﬂickering.
