PT2204-Primary Side CC/CV RegulatorPDF文档下载
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 compensation circuitry. 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.
