Gesamt 2 Seiten C2161 & C2162 flyback controllers  Meet tough new mobile phone no-load requirements to 5 star standard (<30 mW)  Primary Side Sensing flyback controllers eliminate the need for secondary feedback circuitry such as opto- couplers, thereby reducing BOM costs  Meet ENERGY STAR 2.0 and EU Code of Conduct V4.0 efficiency requirements (Level V) Overview CamSemi C2161 and C2162 primary side sensing (PSS) quasi-resonant flyback controllers are aimed at applications up to 8 watts. These two controllers offer very low no-load power requirements found in today’s applications, such as mobile phone chargers, but also easily programmable frequency, cable compensation, quasi-resonant switching and protection features.
