• 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

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.

Figure 6. Typical Waveforms for (1) Normal Operation, (2) Auto-restart, and (3) Power Down Reset.
The leading edge blanking circuit inhibits the current limit
comparator for a short time after the output MOSFET is
turned on. The leading edge blanking time has been set so
that current spikes caused by primary-side capacitances
and secondary-side rectifier reverse recovery time will not
cause premature termination of the switching pulse.
The current limit can be lower for a short period after the
leading edge blanking time as shown in Figure 12. This is
due to dynamic characteristics of the MOSFET. To avoid trig-
gering the current limit in normal operation, the drain current
waveform should stay within the envelope shown.
Shutdown/Auto-restart
To minimize TOPSwitch power dissipation, the shutdown/
auto-restart circuit turns the power supply on and off at an
auto-restart duty cycle of typically 5% if an out of regulation
condition persists. Loss of regulation interrupts the external
schuurrnetnmt iondtoetthoethCeOhNyTsRteOreLtipcina.uVtoC-rreegstualrattimonodcehadnegsecsribfreodm

Overtemperature Protection
Temperature protection is provided by a precision analog
circuit that turns the output MOSFET off when the junction
temperature exceeds the thermal shutdown temperature
(typically 135 °C). Activating the power-up reset circuit by
removing and restoring input power or momentarily pulling
the CONTROL pin below the power-up reset threshold resets
the latch and allows TOPSwitch to resume normal power
