Description
The second generation TOPSwitchTM-ll family is more cost effective and provides several enhancements over the first generation TOPSwitch family. The TOPSwitch-ll family extends the power range from 100W to 150W for 100/115/230 VAC input and from 50W to 9oW for 85-265 VAC universal input. This brings TOPSwitch 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 thedesign 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. TOPSwitch 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.
