Switcher IC TOP222YN (4PCS)

TOP222YN IC – Power Integrations – Off Line Switcher IC

TOP222YN belongs to TOP Switch-II Family from the manufacturer “Power Integration”. It is three-Terminal Off-Line PWM Switch. Description The second generation TOP Switch™-II family is more cost effective and provides several enhancements over the first generation TOP Switch family. The TOP Switch-II family extends the power range from 100W to 150W for 100/115/ 230 VAC input and from 50W to 90W for 85-265 VAC universal input. This brings TOP Switch technology advantages to many new applications, i.e. TV, Monitor, Audio amplifiers, etc. Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even easier. The standard 8L PDIP package option reduces cost in lower power, high efficiency applications. The internal lead frame of this package uses six of its pins to transfer heat from the chip directly to the board, eliminating the cost of a heat sink. TOP Switch incorporates all functions necessary for a switched mode control system into a three terminal monolithic IC: power MOSFET, PWM controller, high voltage start up circuit, loop compensation and fault protection circuitry.
