1 of Enlarge image

Dubbed the market’s first digital PFC controller with power metering offering interleaving and bridgeless functionality, the ADP1048 employs conventional, continuous-conduction-mode PFC techniques to reduce harmonic distortion. It is configurable as an interleaved design to reduce inductor size and replace the rectifier to improve efficiency in bridgeless boost mode. Programming is via an intuitive graphical-user interface that requires no complex code programming skills. Other features include a power metering accuracy of ±3% percent at full load current and an operating temperature range from -40°C to +85°C. Available in a 24-lead QSOP, price is $3.60 each/1,000.
