TOP224P Three-terminal Off-line PWM Switch
Product Highlights • Lowest cost, lowest component count switcher solution
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 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. ABSOLUTE MAXIMUM RATINGS DRAIN Voltage ............................................ -0.3 to
700 V Operating Junction Temperature(3) ................ -40 to 150 °C Typical Performance Characteristics
