TOPSwitch™-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device. Y Package Option for TOP259-261 In order to improve noise-immunity on large TOPSwitch-HX Y package parts, the F pin has been removed .
down extends line surge limit
• Accurate programmable current limit
• Optimized line feed-forward for line ripple rejection
• 132 kHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size
• Half frequency option for video applications
• Frequency jittering reduces EMI filter cost
