Overview
Description
High PF and Low THD
The iW2206 boost PFC controller uses Dialog's PF-BoostTM to provide high power factor (>0.9) and low THD (<10%) at full load across the input voltage range, and it can enable solutions that meet the IEC61000-3-2 requirements for harmonic currents. The device consumes less than 150mW no-load standby power at 230VAC for designs up to 100W of output power, making it ideal for 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.
