TOP247YN Power Integrations Off-line Switcher ICTOP Switch 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 features have been included to lower system costs while also improving design flexibility, performance, and energy efficiency. It has the following transparent characteristics: Soft start, 132 kHz switching frequency (automatically lowered at
