This pin acts as a low noise path for >600 mW output at 110 VAC input the C pin capacitor and the X pin resistor. It is only required for >500 mW output at 265 VAC input the TOP259-261YN package parts. Description TOPSwitch-HX cost effectively incorporates a 700 V power + AC DC MOSFET, high voltage switched current source, PWM control, IN OUT oscillator, thermal shutdown circuit, fault protection and other - control circuitry onto a monolithic device.

In some applications TOP262 may run cooler than TOP261 due to a lower R for the larger device. DS(ON) 2 Rev. H 06/13 www.powerint.com
