PT2204 Datasheet PDF

Powtech PT2204

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. The PT2204 provides accurate CV/CC regulation with built in compensation circuitry.

GENERAL DESCRIPTION

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. Integrated line and primary inductance compensation ensures output current free of line voltage and primary inductance variations. More over, the integrated output cord resistance compensation further enhances output voltage accuracy. A complete set of integrated protection functions allows the PT2204 to protect against all fault conditions including output short circuit, line under-voltage, and over temperature shut down. The PT2204 is available in a SOP8 package.
