applications. It is designed for the flyback topology, and
regulates output current without the secondary feedback loop.
regulation with built in compensation circuitry. Integrated line
and primary inductance compensation ensures output current
free of line voltage and primary inductance variations.
allows PT4203 to protect against all fault conditions including
cycle by cycle current limit, output open/short circuit, line
under-voltage, and over temperature shut down.
