iW3636

Single-Stage LED Driver with PFC

Supports Wide Range of Dimming Interfaces

1 Description

The iW3636 is a high-performance, single-stage AC/DC power controller for PWM dimmable LED driver with power

factor (PF) correction. It supports most commonly used isolated and non-isolated ﬂyback and buck-boost topologies.

The device operates in constant on-time mode to achieve high power factor (> 0.9) across a wide load range. It uses

Renesas’ PrimAccurate™ advanced primary-side sensing technology to achieve excellent output current regulation

over line and load variation without the need for secondary feedback components. It also eliminates the need for external

loop compensation while maintaining stability over all operating conditions.

The iW3636 oﬀers a 1% to 100% dimming range and provides a dedicated PWM dimming input pin that supports a

wide variety of dimming application interfaces such as wireless modules, MCUs or 0-10V interfaces. When working

with Renesas’ secondary-side SSL PWM signal generator IC, the iW339, the iW3636 adopts a proprietary technique to

support accurate dimming by eliminating the impact from the non-ideal characteristics of optocouplers. In addition, the

iW3636 accepts a secondary PWM or analog input to allow maximum output current conﬁguration control.

Renesas’ innovative proprietary technology maximizes the iW3636 performance in an SOIC-8 package. It provides two

multi-function pins to conﬁgure IC functions such as the dimming curve and minimum dimming level. The iW3636 also

enables the active start-up scheme to achieve the shortest possible start-up time without sacriﬁcing active eﬃciency. By

adaptively controlling the maximum operating frequency at diﬀerent dimming levels, it helps eliminate audible noise and

achieve low standby power consumption.
