Datasheet Summary
Primary Side CC/CV Regulator
GENERAL DESCRIPTION
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 meet all the global energy efficiency and standby power requirements. The PT2203 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...
