PT2203
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 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 PT2203 to protect against all fault conditions
including output short circuit, line under-voltage, and
over temperature shut down.
The PT2203 is available in a SOP-8 package.
