iW2206

Power Factor Boost Controller for AC/DC Power Supplies up to 250W and Power Conversion in SSL Lighting

A team of engineers is ready to answer your questions

High PF and Low THD

The iW2206 boost PFC controller provides high power factor (PF > 0.9) and low THD (< 10%) at full load across the input voltage range using Dialog’s PF-Boost™ technology. The device consumes less than 150mW no-load standby power at 230VAC up to 100W of output power, making it ideal for front-end power applications in high-power USB Type-C™ adapters and hubs in solid state lighting, where the front-end converter is always on.

The iW2206 integrates a full range of protection features including output over-voltage, over-power, input over-voltage and under-voltage, over-current and sense resistor short circuit protection, open loop and over temperature protection. The device comes in a tiny SOT23-6 package, enabling a smaller total solution size.
