GENERAL DESCRIPTION

Integrated primary inductance compensation circuitry provides accurate constant current operation despite variations in primary inductance. Excellent EMI performance is achieved with frequency jittering function together with soft driving control at totem pole gate drive output. The device also features a complete set of protection functions to protect against all fault conditions including output open/short circuit, line under-voltage, and over temperature. The PT4213 is available in an SOT23-6 package.
