Datasheet Summary
Primary Side CC/CV Regulator
GENERAL DESCRIPTION
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 global energy efficiency and standby power requirements. The PT2204 provides accurate CV/CC regulation with built in pensation circuitry. Integrated line and primary inductance pensation ensures output current free of line voltage and primary inductance variations. More over, the...
