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.
Product Highlights
Lowest cost, lowest component count switcher solution
Cost competitive with linears above 5W
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 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
