C2161PX2 and C2162PX2 Datasheet
Primary Sensing SMPS Controller For Offline Applications
Constant Voltage and Constant Current (CV/CC) Operation
The C2161PX2 and C2162PX2 controllers achieve constant voltage and constant current output within tight
limits without the need for any secondary sensing components, by sensing the primary side waveforms of
transformer voltage and primary switch current. Figure 6 shows the output characteristics of a typical phone
charger implemented with the C2161PX2 and C2162PX2.
