A new high voltage PMOS with a monolithic current/thermal sensor, and a start-up circuit has been developed to build a power integrated circuit to be co-packaged with a standard low voltage PWM controller. The integration of the start-up circuit, removing the high voltage from the controller chip and minimizing the high voltage external components, allow to obtain a high performance, low cost, hybrid solution for the next-generation off-line SMPS power IC converter. This device can be easily made by conventional high voltage PMOS fabrication process.
