CamSemi flyback controller offers fast load pull-up
CamSemi has designed a primary side sensing (PSS) flyback controller which provides a constant power (CP) operating mode.
C2283 has been designed to offer fast load pull-up of electronic products with high input capacitance, such as modems.
It can be used for universal input adapter applications rated above 8W.
Intended for voltage-regulated supplies, the PSS controller architecture has been developed to boost light load efficiency and to integrate a constant power mode to help with more efficient power level selection.
The C2283, which is packaged in SOT23-6, is the second of the suppler’s PSS controllers to offer fast load pull-up for networking applications.
C2283 has been specifically designed for use with high capacitance loads that deliver longer hold-up times to ride through mains-power disruptions, whereas the earlier device, the C2183 is a general-purpose controller for more typical loads and battery-charger applications.
