Description
General part information
iW3631 Series
The iW3631 two-stage LED driver is a dimmable digital offline PWM controller for solid-state lighting applications up to 120W with high power factor (PF >0.95) and low THD (<10%). It features a built-in driver for isolation transformers that enables direct, 0-10V dimming without the need for an external MCU and driver circuit, reducing cost and complexity. The iW3631 can also be implemented to support a PWM dimming interface to simplify use in wireless SSL applications.
The iW3631 operates in a quasi-resonant mode to provide high efficiency and uses Renesas' PrimAccurate™ advanced primary-side sensing technology to achieve excellent line and load regulation without secondary feedback components. The digital control algorithms used by the iW3631 maintain stability over all operating conditions without the need for any external loop compensation components, minimizing the BOM cost.
The iW3631 can be paired with Renesas'iW3373-in-1 dimming interface.
