PT2204 - Powtech

PT2204 Primary Side CC/CV Regulator

The PT2204 is a primary side constant current/voltage regulator, targeted to sub 4W AC-DC power suppliers applications. 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 PT2204 to meet all the globa.
