DESCRIPTION
The second generation TOPSwitch-II family is more cost effective and provides several enhancements over the first generation TOPSwitch family. TV, Monitor, Audio amplifiers, etc. Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even AC IN D TOPSwitch CONTROL C S Figure 1. Typical Flyback Application. PI-1951-091996 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.
