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 optocouplers, 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.
