PT2208 - PowTech

PT2208 Primary Side CC/CV Regulator

The PT2208 is a high performance AC/DC power supply controller which integrates a 730V power switch. PT2208 is targeted to 5-7W designed for flyback topology, and regulates output current/voltage without the secondary feedback loop. The ultra-low operating current at light load ensures that the PT2208 is ideal for applications targeting the newest regulatory.
