iW3622

Non-dimmable LED driver

The iW3622 integrates high power factor (PF), low output ripple and low total harmonic distortion (THD) in a single-stage SSL LED driver for isolated and non-isolated, high-power, non-dimmable LED replacement bulbs and LED ballasts.

The iW3622 integrates a unique hybrid control scheme with configurable power factor between >0.7 and >0.95, to manage the trade-off between PF and LED output current ripple. This unique feature enables high PF and low ripple in a low-cost solution. And, by using a MOSFET switch, the device is capable of driving LEDs in solutions up to 45W output power. The iW3622 reduces the BOM cost and solution size by incorporating Dialog’s proprietary PrimAccurate™ technology, eliminating the need for a secondary-side regulator and optical feedback isolator. Dialog's advanced technology allows for the functionality and performance of an 8-pin part in a small SOT23 6-pin package.
