PT2204
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 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.
