TOPSwitch-GX uses the same proven topology as TOPSwitch,  
cost effectively integrating the high voltage power MOSFET,  
PWM control, fault protection and other control circuitry onto  
a single CMOS chip. Many new functions are integrated to

Depending on package type, either 1 or 3 additional pins over  
the TOPSwitch standard DRAIN, SOURCE and CONTROL  
terminals allow the following functions: line sensing (OV/UV,  
line feed-forward/DCMAX reduction), accurate externally set  
current limit, remote ON/OFF, synchronization to an external  
lower frequency, and frequency selection (132 kHz/66 kHz).  
All package types provide the following transparent features:

addition, all critical parameters (i.e. current limit, frequency,  
PWM gain) have tighter temperature and absolute tolerances
