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 protec-
tion circuitry.
Product Highlights
• Lowest cost, lowest component count switcher solution
• Cost competitive with linears above 5 W
• Very low AC/DC losses – up to 90% efficiency
• Built-in Auto-restart and Current limiting
• Latching Thermal shutdown for system level protection
• Implements Flyback, Forward, Boost or Buck topology
• Works with primary or opto feedback
• Stable in discontinuous or continuous conduction mode
• Source connected tab for low EMI
• Circuit simplicity and Design Tools reduce time to market
Description
The second generation TOPSwitch™-II family is more cost
effective and provides several enhancements over the first
generation TOPSwitch family. The TOPSwitch-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 univer-
sal 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
