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.
