Description

Figure 1. Typical Flyback Application.

The second generation TOPSwitch-II family is more cost

effective and provides several enhancements over the first

generationTOPSwitchfamily. TheTOPSwitch-IIfamilyextends

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 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 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.

TOPSwitch incorporates all functions necessary for a switched

modecontrolsystemintoathreeterminalmonolithicIC:power

MOSFET, PWM controller, high voltage start up circuit, loop

compensation and fault protection circuitry.
