PT2203 - PowTech

PT2203 Primary Side CC/CV Regulator

The PT2203 is a primary side constant current/current voltage regulator, targeted to applications in less than 5W AC-DC power suppliers. It is designed for the flyback topology, and regulates output current/voltage without the secondary feedback loop. In addition to providing the tight output regulation, the excellent low power control allows the PT2203 to m.
